Last year, the SCCRC granted the man convicted of the Lockerbie bombing a second appeal on the basis that his conviction may have been unsafe. Among the grounds justifying the decision, the Committee stated that the Crown had not given the defense access to a secret document which may be vital to establish the innocence of Megrahi.
The Westminster Government, not the Lord Advocate, has imposed a Public Interest Immunity certificate in order to prevent the defense to see the very document which justifies the second appeal in the first place.
