SEATTLE (AP) — A judge has sanctioned the lawyer for the man who accused Seattle Mayor Ed Murray of sexually molesting him when he was a teenager for "flagrant" violations of ethical rules.

The Seattle Times reports the judge on Thursday fined lawyer Lincoln Beauregard $5,000 for violating the rules of civil procedure.

King County Superior Court Judge Veronica Alicea-Galvan said she'll take Beauregard's ability to file documents if his conduct continues. Beauregard said he respectfully disagrees with the ruling and will appeal.

Beauregard filed a lawsuit on April 4 claiming Murray paid the man for sex when he was a teenage dropout in the 1980s. Murray has vehemently denied the allegations, saying they are politically motivated. Murray's lawyer has twice called for sanctions against Beauregard, accusing him of trying to generate negative publicity against Murray.
