The 2267 court-martial of Spock for mutiny after he abducted the disabled Christopher Pike and took the Enterprise to the forbidden planet Talos IV.
The court-martial is the frame of the two-part original series episode The Menagerie. Spock fakes orders, takes his former captain, Fleet Captain Pike, from Starbase 11 and locks the Enterprise on course for Talos IV, a world closed by General Order 7 on pain of death. He then gives himself up.
A board of Kirk, Commodore Mendez and Pike hears the case as the ship travels. In his defence Spock shows images of Pike's visit to Talos IV thirteen years before, which prove to be sent by the Talosians.
At Talos it emerges that the Mendez aboard was an illusion, used to keep Kirk from regaining control too soon. The real Mendez sends word that the order is suspended for this occasion. Pike chooses to stay with the Talosians, and no action is taken against Spock.
