Dr. Conrad Murray has claimed his conviction for the manslaughter of Michael Jackson should be overturned.

The physician - who has been jailed for four years over the 'Thriller' singer's death - has filed legal documentation in court claiming the judge should allow him to prove Michael was so stressed over his financial affairs he recklessly gambled his life by administering a large dose of anaesthetic Propofol, according to TMZ.com

In a section of the legal documents titled 'Financial Condition of Michael Jackson', Murray's lawyer said: ''Mr. Jackson was in debt approximately $440 million and desperately needed to fulfil a contractual commitment to The O2 Arena in London.

''He was on the verge of losing his entire estate to foreclosure. The pressure to fight through his insomnia, to rehearse and be the entertainer he was in his earlier years was overwhelming.

''His motivation and resulting desperation were relevant to show a likelihood or reason to act in a manner inconsistent with good judgement.''

The filing comes just a day after a District Attorney claimed Dr. Murray was a danger to society and a flight risk, adding he had not shown any remorse for his ''reckless and criminal conduct that directly caused Michael Jackson's death''.
