On May 27, Supreme Court Justice Anthony Kennedy announced his retirement, effective July 31, 2018. This announcement follows last week’s 5-4 decision in South Dakota v. Wayfair, authored by Justice Kennedy, which reversed the physical presence requirement originally established in National Bellas Hess and reaffirmed in Quill. Other important tax (and tax-related) cases have decided by the Supreme Court during Justice Kennedy’s tenure include: Commissioner v. Clark, 489 US 726 (1989); United States v. Goodyear, 493 US 132 (1989); Commissioner v. Soliman, 506 US 168 (1993); Commissioner v. Banks, 543 US 426 (2005); United States v. Home Concrete & Supply, LLC, 566 US 478 (2012); Obergefell v. Hodges, Sup. Ct. Dkt. No. 14-566 (2015); and Pereira v. Sessions, No. 17-459 (2018).

Justice Kennedy was appointed by President Ronald Reagan, and sworn in on February 18, 1988. He won unanimous confirmation. Although considered a conservative jurist, he was also the swing vote in favor of various social issues including same-sex marriage and the right to seek an abortion.

President Trump has already begun the search for Justice Kennedy’s replacement, but confirmation of the president’s nomination will not come without a serious fight. Indeed, whomever President Trump nominates, we can expect the same level of bipartisan animosity for the confirmation hearings as has marred his presidency thus far. Of course, any confirmation will require the Senate’s approval, and given the erosion of a conservative majority in the Senate, confirmation will be no small feat!
