Government takes rendition 'very seriously'
Justice Secretary Kenny MacAskill said the Scottish government took allegations of rendition "very seriously" during topical questions on 28 May 2013.
A study has claimed Wick, Aberdeen and Inverness airports were used in the rendition of terrorist suspects.
The CIA programme involved the secret detention and transfer of terror suspects to other countries for interrogation and alleged torture.
Researchers at the universities of Kent and Kingston studied thousands of flights suspected of being involved.
They concluded that 13 planes with links to the CIA operation touched down at the airports.
Green MSP Patrick Harvie called on the Scottish government to take a proactive approach to the allegations.
Independent MSP John Finnie has written to the Lord Advocate seeking a criminal investigation into the use of Scottish airports.
Mr MacAskill replied that until information was received by the Crown action could not be taken.
Health Secretary Alex Neil then confirmed the Scottish government would introduce legislation to allow same sex marriage within a month.
A consultation on the proposed Marriage and Civil Partnership Bill closed in March, but the responses have not been published.
