The U.S. Judicial Conference has adopted a private seminars disclosure reporting policy (pdf) that requires educational program providers and judges to disclose certain information relevant to judges' attendance at privately-funded educational programs.
Any organization covered by the policy that issues an invitation to a federal judge to attend an educational program as a speaker, panelist, or attendee and offers to pay for or reimburse that judge in excess of $415 must disclose financial and program information.
