Those challenging major rules often try to do so in courts that they perceive will be friendly to their side. In recent years, many court watchers have noticed and lamented an increase in “forum shopping” in litigation over federal agency actions. Of course, many federal statutes require that certain challenges to agency actions be filed in a specific court. Absent such statute-specific venue provisions, however, litigants often have a wide range of options.
While around half of all challenges to major rules were filed in the U.S. District Court for the District of Columbia or the U.S. Court of Appeals for the D.C. Circuit, these courts’ preeminence declined over time. The D.C. Circuit’s decline was starkest, dropping from 53.2% for challenges to the Clinton Administration’s major rules to 38.1% for W. Bush, 27.7% for Obama, and 11.7% for Trump.
