Are Judges Influenced By Dollar Amounts? Evidence From Tax Law, Jonathan Farrar, Thomas Farrar, Harjot Mehmi

Dalhousie Law Journal

We investigate whether idiosyncratic features of numbers in dollar amounts unconsciously bias judges. If so, appellants’ likelihood of success could depend on the dollar amount under dispute. Specifically, we examine the following: whether the first digit in a dollar amount follows the frequency distribution predicted by Benford’s Law, and, accordingly, whether the likelihood of appellants’ success varies with the first digit of their disputed dollar amount; round number bias, which is the psychological tendency to prefer round numbers (ending in 0) over other numbers; and even-odd number bias, which is the psychological tendency to ascribe different characteristics to even numbers …

Allocative Justice As A Constraint On Fiscal Imperialism In International Tax, Okanga Ogbu Okanga, Kim Brooks

Articles, Book Chapters, & Popular Press

Taxpayers’ cross-border activities often result in two (or more) states claiming the right to tax their income. To address concerns about how those tax liabilities might aggregate and suppress international activities, states typically agree to split the tax base between them. But how can states fairly share tax revenue from cross-border activities? Tax scholars and policymakers offer different normative perspectives to address this inter-nation equity conundrum. In this article, we conceptualize these normative perspectives into two types. One centres on identifying where the economic factors that lead to the ability to produce the income are located (and uses that determination …

Tax Treaty Arbitration: An Unacceptable Surrender Of National Sovereignty Or An Expression Of Sovereign Power?, Kim Brooks, Richard Krever

Articles, Book Chapters, & Popular Press

The release in 2016 by the Organisation for Economic Co-operation and Development of a draft multilateral treaty to modify thousands of global bilateral tax treaties was met with surprisingly strong support by the international community, with many states signing, ratifying, and implementing the treaty. One of the treaty’s most contentious elements is the addition to the dispute resolution measures in bilateral treaties, a process known as mutual agreement procedure, of a mandatory arbitration procedure that is to be available where agreement cannot be reached under the conventional process. In contrast to the mutual agreement procedure, which includes no requirement that …

Twenty Years After Krieger V Law Society Of Alberta: Law Society Discipline Of Crown Prosecutors And Government Lawyers, Andrew Flavelle Martin

Articles, Book Chapters, & Popular Press

Krieger v. Law Society of Alberta held that provincial and territorial law societies have disciplinary jurisdiction over Crown prosecutors for conduct outside of prosecutorial discretion. The reasoning in Krieger would also apply to government lawyers. The apparent consensus is that law societies rarely exercise that jurisdiction. But in those rare instances, what conduct do Canadian law societies discipline Crown prosecutors and government lawyers for? In this article, I canvass reported disciplinary decisions to demonstrate that, while law societies sometimes discipline Crown prosecutors for violations unique to those lawyers, they often do so for violations applicable to all lawyers — particularly …

Are The Imposed Principles Standard? A Review Of Imposing Standards: The North-South Dimension To Global Tax Politics By Martin Hearson, Opeyemi Bello

Dalhousie Law Journal

The publication of Martin Hearson’s book, Imposing Standards: The North-South Dimension to Global Tax Politics, coincided with heated international discussions of the most substantial policy proposals in the field of international taxation in the last century.1 Hearson’s work provides insights on how the developed countries exerted control over the negotiations of the double taxation agreement (DTA) regime, which is the basis of the current international taxation framework. It explains how the negotiations resulted in a framework that works well for the developed countries, but does not substantially address the tax revenue needs of the developing countries. The publication of the …

Lower-Income Countries’ Ongoing Quest For International Tax Justice: A Case Study Of The Oecd’S Tax Allocation Proposal, Okanga Ogbu Okanga, Kim Brooks

Articles, Book Chapters, & Popular Press

The viability of our international tax system hinges on two things: (1) safeguarding the effective flow of international activities and (2) ensuring that countries can adequately collect tax on the income derived from those activities. Each of these fundamentals relies on a defensible/fair allocation of taxing rights between countries with competing tax jurisdiction (inter-nation equity).

The recent Organisation for Economic Co-operation and Development (OECD)-led multilateral effort to transform international tax rules to ensure that countries can adequately tax multinational enterprises (MNEs) operating in the global digital economy (OECD proposal) has reignited inter-nation equity conversations. Although important to all countries, inter-nation …

Fostering Implementation Of The United Nations Sustainable Development Goals In Africa: Prospects Of Revenue Generation Under The Tax Treaties Signed By Nigeria, Tanzania, And Botswana, Oladiwura Ayeyemi Eyitayo-Oyesode

PhD Dissertations

African countries are behind in social and economic development. The citizens of these countries experience high levels of poverty and hunger, unemployment, maternal and infant mortality, lack of access to quality education, gender inequality and other social, economic and environmental ills. To fix these development challenges, African countries have been encouraged to improve on domestic resource mobilization. This is regarded as a more viable and sustainable way of actualizing the UN Sustainable Development Goals (SDGs) against reliance on aids and grants. Also, emphasis is placed on taxation as the primary source of revenue for funding development because it ensures ownership …

Disabusing The Tax Aid Narrative: What Inter-National Tax Equity Really Means For "Poor" Countries And How To (Re)Frame It, Ogbu Okanga Okanga

PhD Dissertations

International tax regimes (e.g., the “double taxation regime”) are created by states with competing tax jurisdiction to coordinate their tax rules and, specifically, to address common efficiency problems like international double taxation. In developing such regimes, states attempt to balance competing tax policy priorities: efficiency, administrability, and equity. This work engages with equity, as a policy norm of international tax (inter-national tax equity). It is my thesis that the framing/articulation of inter-national tax equity suffers from a narrative problem that, perhaps, stems from its apparent conceptual unclarity and multifarious usage. This narrative problem is most evident in the articulation of …

Negotiating Bilateral Tax Treaties: Should Tax Treaties Involving Low-Income Countries Contain A Sunset Clause?, Okanga Ogbu Okanga

Reports & Public Policy Documents

This policy brief reflects on an underexplored proposition: that bilateral tax treaties – particularly treaties involving (middle- and) low-income countries – should contain an expiration or sunset clause. The brief examines some reasons why it may be sensible for a low-income country to make its bilateral tax treaty expirable, from its onset. It also highlights a few reasons why such a policy may not be advisable – or tenable. The brief concludes by exploring the design of a model sunset clause for inclusion in the UN Model Tax Convention.

Fiscal Decolonization-Indigenous Fiscal Autonomy And Tax Jurisdiction, Riad Kherallah

LLM Theses

This thesis focuses on the relationship between Indigenous fiscal autonomy and self-determination. Indigenous nations’ ability to achieve self-determination is dependent upon their ability to autonomously finance self-government. Unfortunately, Canada’s colonial policies have weakened Indigenous economies and rendered them dependent upon the Crown. Due to Indigenous nations’ lack of fiscal autonomy, Crown policies designed to promote Indigenous self-government have proven inadequate. This thesis argues for using the United Nations Declaration on the Rights of Indigenous Peoples as a blueprint for developing more equitable economic relations. While there are various elements to Crown-Indigenous economic relations, this thesis focuses on the distribution of …

Domestic Revenue Mobilization Through Corporate Income Tax In An East African Developing Country Context, Afton Titus

Dalhousie Law Journal

The laudable objective of making the Sustainable Development Goals (SDGs) a reality requires the targeted use of financial resources. It has become imperative for governments to raise such financial resources through mechanisms that facilitate the domestic mobilization of revenues. This paper argues that in an African developing country context, corporate income tax represents the most effective means by which governments may raise the required funds. Corporate income tax remains an important source of revenue for African countries. This paper further proposes: (i) the design of the essential features of a corporate income tax system that properly accounts for the economy …

International Tax Law Between Loyalty, Exit, And Voice, Tarcísio Diniz Magalhães

Dalhousie Law Journal

Discourse on the merits and pitfalls of multilateral cooperation for advancing justice in international tax law have recently re-emerged in the literature. Some tax scholars, even while criticizing global projects like the OECD/G20 initiatives on base erosion, profit shifting and the tax challenges arising from the digitalisation of the economy, insist that cooperative efforts herald a step in the right direction. Others contest the feasibility of international cooperation or its value for developing countries. Drawing on Albert Hirschman’s oft-cited framework for actor behaviour under institutional malperformance, this article shows that there are three alternatives for those discontented with the status …

Cross-Border Tax Transparency: A Study Of Recent Policy Developments In Turkey, Leyla Ateş

Dalhousie Law Journal

Transnational tax information cooperation has the crucial role of empowering tax administrations to collect tax revenues in full and on time, thereby narrowing the tax gap created by international evasion and avoidance. However, the adequacy of established transnational tax information exchange systems in combatting international tax evasion and avoidance has been severely criticized and a new wave of progress on transparency has started after the 2008 global economic crisis. In this direction, Turkey set cross-border tax transparency high on its political agenda. Though, Turkey has operationalized new transnational tax cooperation agreements very slowly. Furthermore, Turkey’s approach to exchanging information has …

Origin And Differentiation In International Income Allocation, Ivan Ozai

Dalhousie Law Journal

The present international tax rules are typically justified by origin-based theories. These theories align countries’ tax entitlements with the geographical location of the economic factors that contribute to the creation of income. Two recent phenomena have rendered origin-based approaches limited in scope. First, the economic integration of multinational corporations and the relevance of intangibles have made it infeasible to precisely pinpoint the factors contributing to the generation of income. Second, the growing disputes between countries about which economic factors should be considered relevant for sharing the international tax base have recently led to increased consideration of distributional consequences, thus moving …

Designing A More Sustainable Global Tax System, Allison Christians

Dalhousie Law Journal

The international tax system incentivizes unsustainable business practices because it ignores the private profits created by externalizing human, societal, and environmental costs. This paper proposes a novel reform: applying living wage and externality assessment tools to the rules for establishing where income arises for tax purposes. To do so, I propose a method that is relatively complex but arguably more accurate (in tax terms) and a complementary but relatively simpler proxy method. I examine how each method would implicate treaty-based and domestic rules and processes and conclude that the proposed design provides a viable starting point to make the global …

Testing For Consistency: Certain Digital Tax Measures And Wto Non-Discrimination, Okanga Ogbu Okanga

Articles, Book Chapters, & Popular Press

Few issues have challenged tax policymakers and commentators as much as digital taxation has in recent years. Ongoing efforts to reconstruct the rules of international tax to “properly” govern the taxation of the global digital economy have evoked some important tax and trade related considerations. As regards the latter, unilateral attempts by various states – partly spurred on by a lack of multilateral consensus – to tax nonresident digitalized businesses threaten to disrupt international trade relations, with threats of trade war exchanged between some World Trade Organization (WTO) member states over the propriety of the proposed tax measures. As the …

Taxing Capital In The Age Of Intangibles, Eurallyah Akinyi, Dan Ciuriak

Articles, Book Chapters, & Popular Press

The rise of the intangibles economy has led to a significant erosion of corporate tax revenue in the innovation-intensive advanced economies, even as the share of national income flowing to capital rose. For developing countries, the erosion is worse and comes on top of substantial erosion of corporate tax revenues from the tangibles economy due to weak tax administration and corruption. In this paper, we take up the questions of how big is the taxing problem that the intangibles economy has raised, and whose problem is it. Further, we consider how well the proposed OECD/G20 Inclusive Framework measures up in …

Effective Taxation In Africa: Confronting Systemic Vulnerability Through Inclusive Global Tax Governance, Okanga Ogbu Okanga, Lyla Latif

Articles, Book Chapters, & Popular Press

Implicit within the African fiscal architecture are embedded vulnerabilities to exogenous factors which challenge their domestic revenue mobilization (DRM) strategies. These DRM challenges are attributable to asymmetrical power relationships that exist within the international tax regime (ITR). The rules governing international taxation have largely been devised by developed countries resonating their own economic purposes, resulting in a regressive relationship that overlooks African perspectives in the creation of tax norms. Consequently, policymaking, and scholarship have focused extensively on curbing these power asymmetries that have resulted in vulnerable African tax systems. Continental and domestic approaches are now aligned towards fostering reform of …

Trust And Efficiency In Tax Administration: The Silent Role Of Policy-Based Legitimate Expectation In Nigeria, Okanga Ogbu Okanga

Articles, Book Chapters, & Popular Press

The interaction between tax administration, discretion, and legitimate expectation has been widely explored. However, the subject has traditionally been approached from the perspective of legality and deeply focussed on how courts adjudicate cases bordering on the frustration of legitimate expectation by tax authorities. This is unsurprising, given that legitimate expectation evolved as a judicial remedy to check administrative unfairness and to provide certainty and trust in public administration. Cases show that this remedy is rarely accorded by the courts, which makes its efficiency questionable. Using Nigeria as a case study, this doctrinal paper explores the prospects of taking an alternative …

Readability In The Canadian Tax System, Colin Jackson

Articles, Book Chapters, & Popular Press

This paper reports the results of a readability analysis of various parts of the Canadian tax system, with a particular focus on Canada’s income tax. The results indicate that Canada’s Income Tax Act is significantly more difficult to read than the taxation statutes of several comparable jurisdictions and more difficult to read than other Canadian legislation governing economic relationships. The guidance published by the Canada Revenue Agency for the use of tax professionals and the public appears more accessible. While it may be hoped that the statutory provisions that apply to low- and middle-income individuals would be more readable than …

Dispute Settlement Under The African Continental Free Trade Area Agreement: A Preliminary Assessment, Olabisi D. Akinkugbe

Articles, Book Chapters, & Popular Press

The African Continental Free Trade Area Agreement (AfCFTA) will add a new dispute settlement system to the plethora of judicial mechanisms designed to resolve trade disputes in Africa. Against the discontent of Member States and limited impact the existing highly legalized trade dispute settlement mechanisms have had on regional economic integration in Africa, this paper undertakes a preliminary assessment of the AfCFTA Dispute Settlement Mechanism (DSM). In particular, the paper situates the AfCFTA-DSM in the overall discontent and unsupportive practices of African States with highly legalized dispute settlement systems and similar WTO-Styled DSMs among other shortcomings. Notwithstanding the transplantation of …

The Province Of (Substantive) Legitimate Expectation In Nigeria's Tax Administration: A Law And Policy Evaluation, Okanga Ogbu Okanga

LLM Theses

The interplay between tax administration and legitimate expectation has been the subject of debate and scholarship in many jurisdictions. Questions around how much discretion tax authorities should be allowed and whether courts should uphold the (substantive) legitimate expectations of taxpayers – by implication, bind the tax authority – when the tax authority reverses itself on a guidance, promise, position, etc. feature prominently in this conundrum. In Nigeria, the disposition of both the tax authority and the court appears to lean towards outright dismissal of legitimate expectation. Put differently, it seems that the tax authority does not consider itself bound by …

The Political Economy Of Nigeria’S Digital Tax Experiment, Okanga Ogbu Okanga

Articles, Book Chapters, & Popular Press

In January 2020 when I first read Nigeria’s Finance Act 2019, one of the instinctive questions that came to me was “is Nigeria serious about taxing digital trade now”? There were a few reasons for this skepticism. First, the Act seeks to tax nonresident companies (NRCs) that have a “significant economic presence” (SEP) in Nigeria but then delegates the definition of that pivotal phrase. Second, I questioned how Nigeria can enforce/administer this unilateral tax, which is payable by companies outside its borders. Third, I imagined that Nigeria’s unilateral attempt to tax digital trade could undermine relations with a strategic …

Portrait Of A Tax Transplant Artist, Kim Brooks

Articles, Book Chapters, & Popular Press

This article explores the process of norm migration through the study of one tax expert, Victor Thuronyi. It situates the literature on the role of experts in tax norm migration and identifies core themes and gaps in the tax transplant literature; explores five themes, connected to the literature on the role of tax experts and tax transplants, that arise from a study of Victor Thuronyi’s contributions to tax transplantation; and concludes with some reflections on the benefits and challenges of having highly specialized, non-insider tax experts engaged in the exercise of drafting tax laws.

Into The "Vortex Of Legal Precision": Access To Justice, Complexity, And The Canadian Tax System, Colin Jackson

PhD Dissertations

This thesis is an exploration of access to justice issues in the Canadian tax system. Drawing on the work of Roderick Macdonald, it argues for a broad conception of access to justice based on the empowerment of individuals in all of the sites, processes, institutions where law is made, administered, and applied. It argues that tax law shows the usefulness of this comprehensive approach to access to justice. Using the comprehensive approach to access to justice, the thesis goes on to argue that legal complexity should be seen as an important access to justice issue in tax law. It lays …

An Intellectual History Of Comparative Tax Law, Kim Brooks

Articles, Book Chapters, & Popular Press

In this article, the author argues that comparative tax law has an intellectual history. More specifically, the author claims that history reveals there is a distinguishable comparative tax law scholarship where tax scholars engage in common debates. The author then offers a description of method, highlighting the difficulty of identifying the work that might be considered “comparative tax law.” Next, the author conceptualizes and clusters contributions from scholars who have framed the comparative tax law field. The author argues that our national boundedness, combined with the lack of an explicit network of scholars, has masked the rich intellectual history in …
