In 1979 , Anderson was convicted along with Ross Dunn and Paul Alister to 16 years ' imprisonment for an alleged plot by members of the Ananda Marga spiritual movement , plot to bomb the house of Robert Cameron , a member of the far-right National Front of Australia . After almost seven years in prison the three were pardoned and paid a sum in compensation following an inquiry into the convictions in 1985 . However , in a linked case , he was re-arrested in 1989 . In 1990 , Anderson was convicted for three counts of murder for planning the Sydney Hilton Hotel bombing , for which Evan Pederick had been jailed the previous year . Anderson was sentenced to 14 years ' imprisonment , but was acquitted on appeal in 1991 . In directing an acquittal NSW Chief Justice Murray Gleeson said : " The trial of the appellant miscarried principally because of an error which resulted in large part from the failure of the prosecuting authorities adequately to check aspects of the Jayewardene theory . This was compounded by what I regard as an inappropriate and unfair attempt by the Crown to persuade the jury to draw inferences of fact , and accept argumentative suggestions , that were not properly open on the evidence . I do not consider that in those circumstances the Crown should be given a further opportunity to patch up its case against the appellant . It has already made one attempt too many to do that , and I believe that , if that attempt had never been made , there is a strong likelihood that the appellant would have been acquitted "
