Maria Gardiner and Michael Anderson, both sentenced to life with an 18-year punishment part, appealed their convictions for murder, arguing the trial judge misdirected the jury on the applicability of different verdicts for co-accused.

 The attack on the deceased was pre-planned, involving multiple weapons and a clear intention to inflict serious harm. 

The court upheld the trial judge’s ruling that all participants could be found guilty of murder if serious violence was foreseeable, regardless of individual intentions. 

Gardiner’s appeal against the length of her sentence was also rejected, as her involvement in the planning and execution of the attack was deemed significant. 

Ultimately, both appeals were denied, confirming their convictions and sentences.
