Brady and co-accused Dean Byrne are charged with conspiring to persuade a State witness not to testify during Brady's murder trial.

Lisa Smith appeared before the Court of Appeal today through a live video link.

The former Irish soldier was convicted earlier this year following what was described as a 'novel and complex' trial.

She’ll be sentenced on Friday week.

Mr Justice Michael MacGrath said he is satisfied that there is a real risk of interference with witnesses if Mr Treanor is granted bail.

In his action, 41 year-old Alan Harte challenges the constitutionality of Section 40 of the 1939 Offences Against the State Act.

Murray was sentenced to nine years in prison, with the final 18 months suspended.

Two notices of appeal were filed just days after sentencing.
