Lynn was handed a 32-year jail term, with a non-parole period of 24 years, before launching his appeal.
Appeal documents lodged with the Supreme Court in November last year show Lynn will appeal both his conviction and the sentence handed down by Justice Michael Croucher.

Of the five grounds, four relate to Lynn’s conviction and one to his sentence.
Lynn’s defence team say the Crown prosecution launched a “sustained attack” on Lynn’s version of events during the prosecutor’s closing address, which included statements never put to their client during his time in the witness box.
The second appeal ground relates to the evidence of ballistics expert Paul Griffiths, employed by Victoria Police, who brought the murder weapon into court and talked the jury through its operation.

During his evidence, Lynn’s legal team claim Griffiths made a serious departure from the rules that govern fair conduct of criminal trials, one that may have led the jury down an “impermissible pathway” in arriving at a guilty verdict.
Lynn’s lawyers claim the jury’s guilty verdict was “unsafe” and “unsatisfactory” and his sentence manifestly excessive.
Dann said the prosecution’s breaches of fairness on the trial came “so thick and fast” that the defence couldn’t keep up.
The Director of Public Prosecutions Brendan Kissane is appearing for the prosecution.
The appeal hearing continues.
