AUSTIN -

The Texas doctor convicted in the death of pop superstar Michael Jackson has sued the state over stripping his right to practice medicine.

Conrad Murray accuses the Texas Medical Board of prematurely revoking his license. The former Houston cardiologist was released from a California jail this week after serving less than 2 years for involuntary manslaughter.

Murray was convicted in 2011 of giving Jackson a lethal overdose of a powerful anesthetic. But in a lawsuit filed in Austin this week, Murray claims that his conviction isn't final in California until his appeals are exhausted.

Murray states in an affidavit that he's more than $400,000 in debt and can't afford to pay court costs.

A spokesman for the Texas Medical Board did not immediately return a message seeking comment Thursday.
