A lawyer who represented a folk group that tried to stop a Harry Potter movie from being shown in Canada has been disbarred.

Kimberly Townley-Smith had her license revoked by the Law Society of Upper Canada on Tuesday for making unfounded allegations of bias and corruption against judges and others stemming from the Potter case.

A disciplinary panel found her guilty of professional misconduct.

In 2005, Townley-Smith represented a Canadian folk group called The Wyrd Sisters that sued Warner Bros. for $40 million.

The lawsuit claimed that a scene in "Harry Potter And The Goblet of Fire" showed a fictional rock band that infringed on the group's trademark.

Townley-Smith lost the case, setting off years of appeals in which she accused nine judges and more than a dozen lawyers of conspiring against her.
