The Florida Supreme Court is threatening Coral Gables attorney Jack Thompson with sanctions for frivolous and insulting filings in his disciplinary case. The attorney who has made a name for himself crusading against pornography was warned about his filings last April after he submitted “pornographic materials” to the court, the show-cause order said. The Florida Supreme Court issued the order Tuesday telling Thompson to explain why it shouldn’t reject future court filings from him unless they are signed by another Florida Bar member.

Thompson responded with three court filings by Thursday afternoon, according to the Supreme Court’s online docket. The court warned him twice last year to stop filing motions with the court in his disciplinary case assigned to Miami-Dade Circuit Judge Dava Tunis.
