Texas lawmakers exceeded their power when they intervened last month to stop the execution of Robert Roberson by summoning him to testify, the court found.

A Texas Supreme Court has said the execution of Robert Roberson - a Texas man who was convicted of killing his two-year-old daughter - can proceed.

The Texas Supreme Court on Friday said the state could set a new execution date for a man convicted of murdering his toddler on evidence of "shaken baby syndrome," ruling that a legislative committee exceeded its authority in delaying the sentence.

The Texas Supreme Court on Friday said the execution of Robert Roberson, which would be the first over a death from shaken baby syndrome, can move forward after halting it last month.

State lawmakers had stopped Robert Roberson’s execution at the last minute in an unusual legal maneuver.

The Texas Supreme Court on Friday ruled a House committee overstepped its authority when it effectively stalled Robert Roberson’s execution by issuing an eleventh-hour subpoena. The ruling clears the way for prosecutors to seek a new execution date for Roberson.

The Texas Supreme Court has denied lawmakers' bid to use their subpoena power to halt the execution of a death row inmate for his daughter’s “shaken baby” death, paving the way for it to proceed.

Robert Roberson was scheduled to die by lethal injection on Oct. 17 when lawmakers, in a last-ditch effort, issued a subpoena to have him testify at the Texas Capitol days after his planned execution.
