A judge ruled that secret Major League Baseball documents concerning the $2 billion sale of the Los Angeles Dodgers can’t be used by former team owner Frank McCourt’s ex-wife to challenge their divorce settlement, Bloomberg News reported yesterday. Any documents written for use during confidential mediation sessions between the Dodgers, Frank McCourt and league officials will remain secret, ruled Bankruptcy Judge Kevin Gross, who oversaw the team's bankruptcy. By seeking to obtain the documents, Jamie McCourt tried to evade a federal bankruptcy court order to keep the mediation confidential, Judge Gross said. "This is my order and I am enforcing it because it was an essential ingredient in the success" in ending the Dodgers' bankruptcy, Gross said. The Dodgers left bankruptcy last year after Frank McCourt sold the team for a record $2 billion to a group including Guggenheim Partners and its top executive Mark Walter and ex-basketball player Magic Johnson.
