The King of Pop's personal physician, Dr. Conrad Murray, is accused of administering the drug that killed Jackson in June, 2009 and jury selection for the trial is due to begin next week (08Sep11).
Bosses at Jackson's concert promoters, AEG Live, are in the midst of a civil suit with executives at Lloyd's of London over the insurance policy for the Thriller hitmaker's doomed This Is It shows, for which the singer had been preparing for at the time of his death.
That suit requires the parties involved to look over official records surrounding the cause of Jackson's passing - but prosecutors fear disclosure of the documents could cause key information to be leaked to the media before Murray's trial is complete.
Los Angeles Deputy District Attorneys David Walgren and Deborah Brazil made the request to keep the records private in court papers filed on Wednesday (31Aug11), expressing that the case had already received "significant, unrelenting media attention".
Jackson had been insured by Lloyd's of London for £10.9 million for the concert series. Company officials are fighting a pay out, arguing that the singer did not disclose the full list of drugs that he was taking at the time of his death.
