In 2152, after Porthos had urinated on an Alvera tree, T'Pol conveyed the apologies of Porthos' owner Jonathan Archer to the Chancellery. She was informed that this body was considering possible acts of contrition by Archer for this breach of etiquette. (ENT: "A Night in Sickbay")
Background information Edit
According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 443), the act of contrition by Archer, which earned the approval of the Chancellery, was the ritual sectioning of the tree Porthos urinated on.
