The Texas Supreme Court has ruled that lawmakers cannot stop executions through a legislative subpoena after the execution of Robert Roberson was delayed last month.

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.

Robert Roberson has gained bipartisan from lawmakers and medical experts who say he was convicted on faulty evidence of the shaken baby diagnosis.

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 denied a state house committee’s attempt to delay the execution of a man convicted of murder in the 2002 death of his 2-year-old daughter, clearing a path for a new execution date.

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.

It is the latest twist in the political saga surrounding the Roberson case, which drew national attention and sparked fresh rifts within the Republican party.

The state’s highest civil court ruled that legislators can’t use subpoenas to block death row inmates’ executions, but suggested there’s still time for Roberson to testify before a Texas House panel.

The Texas Supreme Court on Friday cleared the way for 57-year-old Robert Roberson to become the first person in the U.S. to be executed for a "shaken baby syndrome" murder. A jury convicted Roberson of killing his 2-year-old daughter in 2002.

The Texas Supreme Court ruled Friday the state Legislature does not have the power to stall an execution, ending a constitutional crisis that erupted after lawmakers subpoenaed Robert Roberson III to testify before a committee four days after he was scheduled to be put to death.
