The only sitting Philadelphia Traffic Court judge who has not been charged by federal prosecutors with conspiring to fix tickets testified Friday that she cooperated with an internal probe and that she was never involved in seeking favorable treatment about tickets as a ward leader.

The Pennsylvania Supreme Court issued a rule to show cause as to why Traffic Court Judge Christine Solomon should not be suspended for 90 days because she allegedly did not cooperate with the consultants paid for by the First Judicial District to assess how ticket-fixing was happening. Chadwick Associates was retained on the matter in the wake of federal raids in the fall of 2011 at the court, judges' homes and judges' businesses.
