Servotronics, Inc. V. Rolls-Royce Plc And The Boeing Company: Brief Of Professor Yanbai Andrea Wang As Amicus Curiae In Support Of Neither Party, Yanbai Andrea Wang, Michael H. Mcginley

Faculty Scholarship at Penn Carey Law

Rather than expressing a view on the issues raised and ably briefed by the parties, amicus submits this brief to inform the Court of the scholarly research she has conducted regarding Section 1782 proceedings since this Court’s seminal decision in Intel. As Section 1782 applications have proliferated, the lower courts have struggled to apply the Intel factors as this Court had envisioned. Especially in the context of Section 1782 applications submitted by parties to an international proceeding (as opposed to those made by the international tribunal itself), lower courts have frequently found themselves unable to analyze and apply the …

Procedure And Pragmatism, Stephen B. Burbank

Faculty Scholarship at Penn Carey Law

In this essay, prepared as part of a festschrift for the Italian scholar, Michele Taruffo, I portray him as a pragmatic realist of the sort described by Richard Posner in his book, Reflections on Judging. Viewing him as such, I salute Taruffo for challenging the established order in domestic and comparative law thinking about civil law systems, the role of lawyers, courts and precedent in those systems, and also for casting the light of the comparative enterprise on common law systems, particularly that in the United States. Speaking as one iconoclast of another, however, I also raise questions about Taruffo’s …
