The Texas Supreme Court ruled that lawmakers cannot use subpoenas to halt Robert Roberson's execution for the alleged murder of his daughter. Despite bipartisan concerns about the conviction based on discredited 'shaken baby syndrome' evidence, Roberson's execution is set to proceed. The ruling highlighted the tension between the legislative and executive branches, emphasizing that older medical knowledge might have unfairly impacted his case. Roberson denies guilt and cites pneumonia as the cause of his daughter’s death, while his conviction is widely debated. No new execution date has been set yet.
