Vulcan law

Vulcan law was the legal system of the Vulcans.

In 2154, Soval was compelled to appear before the Vulcan High Command to answer for his actions in performing a mind meld. (ENT: "The Forge")

As of the 22nd century, treason was one of the few crimes that carried the penalty of execution. Though former Sub-commander T'Pol had joined Starfleet, she was still subject to Vulcan laws, as V'Las reminded her later that year. (ENT: "Kir'Shara")

T'Pring's 2267 divorce of Spock was only possible via the Kal-if-fee. (TOS: "Amok Time")
