In 2012, four federal appeals ­judges enjoyed free legal services from law firms — including Judge Jay Bybee of the Ninth Circuit, for the sixth year in a row — and another 14 had financial agreements with firms they worked for before taking the bench.

These judges represented only a small subset, seven percent, of the 257 federal appeals judges whose mandatory annual financial disclosures were provided to The National Law Journal. The ­lingering financial ties that bind these judges to law firms aren’t prohibited — assuming judges recuse when the relationships ­create potential conflicts of interest.
