A bipartisan coalition of lawmakers had issued a subpoena for Roberson to testify in his "shaken baby" case, setting off a flurry of litigation.

A Texas constitutional crisis erupted after state lawmakers subpoenaed death row inmate Robert Roberson III to testify before a committee four days after

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.

After months of delays and an attempt for clemency​, the execution of Robert Roberson will resume, according to a new filing​ from the Texas Supreme Court.

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 House Committee on Criminal Jurisprudence summoned Roberson to testify about his case, which successfully stayed his October execution with help from the Texas Supreme Court. But the high court says the House overstepped its authority.

The Texas Supreme Court on Friday ruled that a legislative subpoena cannot be used to stop an execution after Republican and Democratic lawmakers used the novel maneuver last month to pause Robert Roberson 's lethal injection at the last minute.
