Houston attorney Steve Pursley, who’s under indictment for federal tax evasion, won a trial continuance on Thursday because he swapped out his defense counsel after an email snafu led his former lawyer to allege that prosecutors tampered with a court record.

The trial was scheduled for Tuesday but will now occur in September to give Pursley’s new attorneys time to prepare for trial. Pursley has pleaded not guilty to charges of conspiracy to defraud the United States and three counts of tax evasion.
