From 1970 to 1975 he served as an Assistant United States Attorney in the Criminal Division in the United States Attorney's Office for the Southern District of New York, where he prosecuted drugs and business fraud cases.

Judicial administration

Walker has served as Special Counsel to the U.S. Administrative Conference (1987–1992) and president of the Federal Judges' Association (1993–1995). As chief judge, Walker was engaged with all three levels of federal court administration. He led the Court of Appeals, chaired the Second Circuit Judicial Council with responsibility for all of the courts within the Second Circuit (consisting of the states of Connecticut, New York, and Vermont), and on the national level was a member of the Judicial Conference of the United States, chaired by the Chief Justice of the United States (2000–2006). He was also selected by Chief Justice William Rehnquist to be a member of the Conference's Executive Committee (2003–2006) and its Budget Committee (1990–1999). He was selected by Chief Justice John G. Roberts Jr. to be a member of its Committee on International Judicial Relations (2006–2012), and to be the Chair of the Conference's Committee on Judicial Conduct and Disability (2009–2013). As Chief Judge of the Second Circuit, Walker managed the dislocations from the courthouse at 40 Foley Square in lower Manhattan caused by the terrorist attacks of 9/11/2001, oversaw the establishment by Judge Jon O. Newman of a separate calendar for a sudden crush of 5,000 immigration appeals in 2005, and obtained funding for the total renovation of the Thurgood Marshall Courthouse at 40 Foley Square which was completed under the supervision of Chief Judge Walker and his successor, Chief Judge Dennis Jacobs.

Court cases Walker has authored several hundred decisions in various areas of federal law including influential precedents in the areas of constitutional law, criminal law, criminal and civil procedure, securities law, bankruptcy law, intellectual property law, and international law, including the following selected appeals.

Constitutional law National Abortion Federation v. Gonzales, 437 F.3d 278, 296 (2d Cir. 2006) (Walker, C.J., concurring). In a concurring opinion, Walker criticized the evidentiary standard adopted by the Supreme Court in Stenberg v. Carhart, 530 U.S. 914 (2000), which allowed facial challenges against abortion laws to succeed with only speculative showings that the challenged regulations might work an unconstitutional result. This standard, Walker observed, was "both unclear and difficult" for lower courts "to apply with any certainty" and left legislatures without sufficient constitutional guidance on how challenges could be made against their enactments. Justice Anthony Kennedy cited Walker's reasoning approvingly in Gonzales v. Carhart, 550 U.S. 124 (2007), which distinguished Stenberg and upheld the constitutionality of the federal partial-birth abortion statute enacted by Congress in 2003. Rweyemamu v. Cote, 520 F.3d 198 (2d Cir. 2008), formally adopting the ministerial exception to Title VII of the Civil Rights Act in the Second Circuit. Rweyemamu was cited favorably by Chief Justice John Roberts in the unanimous opinion of the U.S. Supreme Court in Hosanna-Tabor Evangelical Lutheran Church and School v. Equal Employment Opportunity Commission, 565 U.S. 171 (2012).565 U.S. ___, ___,132 S. Ct. 694, 705 n.2 (2012).

The Ross Institute, 364 F.3d 471 (2d Cir. 2004), deciding whether a fair use defense was available when copyrighted materials were obtained in bad faith. Cartoon Network, LP v.

Judicial philosophy Walker is a strong advocate of judicial independence for both courts in the United States and in other countries. He has condemned the growing politicization of the judicial nomination and confirmation process for federal judges.John M. Walker Jr., "The Unfortunate Politicization of Judicial Confirmation Hearings" The Atlantic, July 9, 2012. The "political theater" that judicial nominees are subjected to in the Senate, he writes, "politicizes the judiciary, misrepresents the judiciary's role in our democracy, demeans highly qualified nominees, and unjustifiably delays or jettisons confirmations." An independent judge, in his view, is one who faithfully applies existing law to the facts of the case at hand, giving due respect to precedent, and resists the temptation to effectively rewrite legislative enactments. The independent judge "must remain detached and impartial -- and free not merely from personal or financial interests" but also free of "any responsibility to party or social faction" and "must not be concerned with whether an outcome will incur public approbation or wrath."

Teaching and scholarship Since 2000, Walker has been a Lecturer in Law at Yale Law School, where he has taught constitutional litigation with fellow Second Circuit judges Guido Calabresi and Susan L. Carney and with district judges Mark Kravitz and Jeffrey Meyer.

From 1996 to 2000, Walker was an adjunct professor at New York University School of Law and a member of NYU's Institute of Judicial Administration and Appellate Judges Seminar. He has also served on the Board of the U.S. Association of Constitutional Law since 1997 and the CEELI Institute in Prague since 2006.

Rule of law initiatives Walker is actively involved in initiatives to promote the rule of law, strengthen judiciaries and foster cooperation among judges around the world, especially in Eastern and Central Europe, China and the Middle East. He was a member of the U.S. delegation to the G8 Experts Conference on the Rule of Law in Berlin in 2007."Experts Conference on the Rule of Law" Federal Foreign Office, Germany, 2007 Accessed August 13, 2013.
