Protecting The ‘Unwanted’: How And Why We Should Defend Former Gang Members In Their Pursuit Of Asylum, Anjani P. Shah Dec 2022

Protecting The ‘Unwanted’: How And Why We Should Defend Former Gang Members In Their Pursuit Of Asylum, Anjani P. Shah

Journal of Law and Policy

This Note discusses the flaws in the tripartite analysis to determine whether an asylum seeker satisfies the protected ground of “membership in a ‘particular social group’” (“PSG”). An applicant seeking a PSG determination must prove: (1) “immutability,” (2) “social distinction,” and (3) “particularity.” This Note argues that when PSG asylum claims are denied and appealed to the Board of Immigration Appeals (“BIA”), the BIA has incoherently tangled what is actually required in order to compel an affirmative PSG determination. One group of asylum seekers that has been significantly disadvantaged by this tripartite test is former gang members. This Note argues …


Hacking Copyright: Holding Cops Accountable For Abusing Youtube’S Copyright Filter System, Tyler Bloom Dec 2022

Hacking Copyright: Holding Cops Accountable For Abusing Youtube’S Copyright Filter System, Tyler Bloom

Journal of Law and Policy

This Note both explores the mechanisms and incentive structures that make “copyright hacking” possible and explains the legal system’s failure to provide recourse for victims of successful “copyright hacks” by police officers. Because the DMCA has failed to keep pace with the internet’s exponential growth, OSPs, such as YouTube, have developed filtering systems that can be exploited to “copyright hack” users and ultimately suppress their speech. A victim of “copyright hacking” by a police officer currently has no recourse; the doctrine of qualified immunity functionally precludes them from suing for violating their First Amendment rights. This Note proposes two possible …


Ice Transfers And The Detention Archipelago, Sabrina Balgamwalla Dec 2022

Ice Transfers And The Detention Archipelago, Sabrina Balgamwalla

Journal of Law and Policy

This article examines transfers as an understudied but critical dimension of the immigration detention system. Transfers regularly take detainees in immigration custody from public to private facilities, across state lines, and beyond the jurisdiction of individual courts. Immigration and Customs Enforcement (“ICE”) has virtually unlimited authority to use transfers strategically to further agency goals of immigration enforcement. For individual detainees, transfers shape outcomes in their immigration cases. Noncitizens are regularly funneled into detention centers in legal jurisdictions generally hostile to claims for relief. Transfers also regularly send detainees to facilities in isolated, rural communities, where they are more likely to …


Unending Reform: Police Resistance To Consent Decrees And Federal Monitors, Finn Mayock Dec 2022

Unending Reform: Police Resistance To Consent Decrees And Federal Monitors, Finn Mayock

Journal of Law and Policy

The murder of George Floyd and the subsequent protests that engulfed the United States in 2020 reignited public attention towards the violent and discriminatory practices of police departments across the country. While methods of reforming these institutions were debated with new vigor, the federal courts have been quietly overseeing efforts to obtain constitutionally compliant policing in numerous cities for decades. Using legal tools such as consent decrees and monitors, the Department of Justice has enlisted the assistance of federal courts to ensure that police practices are in congruence with the Constitution. As pervasive police violence against black and brown people …

Irreducible Representations From Group Actions On Trees, Charlie Liou Dec 2022

Irreducible Representations From Group Actions On Trees, Charlie Liou

Master's Theses

We study the representations of the symmetric group $S_n$ found by acting on

labeled graphs and trees with $n$ vertices. Our main results provide

combinatorial interpretations that give the number of times the irreducible

representations associated with the integer partitions $(n)$ and $(1^n)$ appear

in the representations. We describe a new sign

reversing involution with fixed points that provide a combinatorial

interpretation for the number of times the irreducible associated with the

integer partition $(n-1, 1)$ appears in the representations.
