Klingon was the chosen language for the Welsh government in its response to queries about UFO sightings at Cardiff Airport. While English and Welsh are the usual forms of communications in the Senedd, it opted for the native tongue of the enemies of Star Trek's Captain Kirk.
Shadow Health Minister Darren Millar had asked for details of UFOs sightings and asked if research would be funded.
A Welsh government spokesman responded with: "jang vIDa je due luq. 'ach ghotvam'e' QI'yaH devolve qaS."
In full it said it translated as: "The minister will reply in due course. However this is a non-devolved matter."
It is believed to be the first time the Welsh government has chosen to communicate in Klingon.
Mr Millar, shadow health minister and AM for Clwyd West, submitted three questions to economy, science and transport minister Edwina Hart about UFO reports around the airport and across the rest of Wales.
Responding to the government's unusual diversion into trilingualism, Mr Millar said: "I've always suspected that Labour ministers came from another planet. This response confirms it."
