An appellate board has upheld the disbarment of Charles Sebesta, swatting back his technical argument for why he should retain his bar card after the ex-prosecutor sent an innocent man to death row and hid exculpatory evidence in the process.

Sebesta was disbarred by the State Bar of Texas last year over his conduct during Anthony Graves’ 1994 capital murder trial. The bar concluded that Sebesta failed to provide several items of exculpatory evidence to Graves’ defense attorneys, presented false testimony to the jury and made a false statement of material fact to the trial judge, among other things.
