The United Firefighters Union and its secretary Peter Marshall are behind a legal attempt to stop a report by Victoria's anti-corruption watchdog from being published.The state's highest court today ordered that the identities of parties trying to block the release of the Independent Broad-based Anti-corruption Commission's (IBAC) Operation Richmond report be identified.Last month, two mystery parties made a last-ditch court bid to stop the report from being tabled to Victorian parliament and made public.On Friday, Victoria's Court of Appeal upheld a decision by Supreme Court judge Claire Harris to deny the parties a pseudonym order."Her honour's conclusion was correct," Justice Richard Niall said.In a statement, Mr Marshall said he respected the court's decision."Pseudonyms have often been given in the past to persons challenging the legality of IBAC's conduct However, the Supreme Court held that a differentiating factor in the present case is that 'there is a significant amount of information in the public domain about Operation Richmond'," Mr Marshall said."The Court of Appeal agreed."Mr Marshall said he and the union were prohibited from talking further about the case."Examinations were in private, confidentiality notices were issued
