Murray was desperate to get his 2011 conviction overturned and clear his name in a bid to win back his lost medical license, but unfortunately for the disgraced physician that will not happen.
The former doctor was convicted of administering a lethal dose of the anesthetic Propofol that resulted in the death of Michael Jackson in 2009.
However, Murray had claimed it was the King of Pop himself who had self-administered the anesthetic and this theory, among others, served as the grounds for his appeal.
However, according to TMZ, the California Courts of Appeal upheld Murray's conviction for involuntary manslaughter as they believed his theories that Jackson administered the drug were just theories.
Murray's fingerprints were found all over the infamous drug bottle and this served as sufficient evidence to support his conviction.
According to the BBC, the court said the "Thriller" hit maker was "a vulnerable victim and that [Murray] was in a position of trust and violated the trust relationship by breaching standards of professional conduct in numerous respects."
The ruling went on to state, "Murray's callous disregard for Mr. Jackson's health and safety was shown throughout the trial from the manner in which he administered a number of dangerous drugs to Mr. Jackson without the appropriate medical equipment, precautions or personnel in place."
Conrad Murray won't be practicing medicine again in this lifetime at least.
