TX HB870

Expands the corroboration requirement for controlled substance convictions to include testimony from any person acting covertly on behalf of law enforcement, removing the previous exemption for licensed peace officers and special investigators

Requires that testimony from undercover operatives in drug cases must be supported by other evidence connecting the defendant to the offense before a conviction can occur

Specifies that corroborating evidence must do more than simply prove a crime was committed—it must specifically link the defendant to that crime

Applies to any case in which judgment is entered on or after September 1, 2025; cases with judgments entered before that date remain under former law
