There is an informative piece (behind a paywall, however) in the WSJ about the elimination of faculty positions, mostly through retirements and buy-outs of existing faculty; besides Seton Hall and Vermont, other schools mentioned are:

Hamline University School of Law in St. Paul, Minn….has shrunk its full-time faculty about 18% since 2010, and the school is exploring ways to further scale back its head count. Ten faculty members have retired since the school began offering early-retirement incentives in 2011, and four more have accepted agreements and plan to retire in the coming academic year….

This year's entering class at Hamline is expected to be about 100 students, Mr. Lewis [the Dean] said—a 55% drop from 2010….

Earlier this year, 21 professors accepted buyout packages at Widener University School of Law, which operates campuses in Wilmington, Del., and Harrisburg, Pa. And last fall, the University of Dayton School of Law offered early-retirement packages to 14 professors, seven of whom took them….

At University of the Pacific's McGeorge School of Law in Sacramento, Calif….[s]everal professors have taken buyouts as the school rescales its JD program from 1,000 students to about 600, a size that Dean Jay Mootz said is better suited to the school's regional market….

The article also reports that George Mason, which had a 2012 entering class that was half the size of its 2010 class, is having faculty teach larger classes and not filling staff positions except when necessary.
