Perth man loses appeal over masked attack A PERTH man who was convicted of assaulting a mother at her home after he saw her son hurling eggs around the neighbourhood has had his appeal bid rejected. Adam John Wragg was sentenced late last year to at least two years and six months behind bars for the home invasion in Kardinya on September 22, 2011, during which he assaulted Denise Douglass. The trial was told Wragg saw Ms Douglass' son Khian and a friend throwing eggs at houses and motor vehicles, and followed them home in his car. Soon after, Ms Douglass heard a vehicle stop in the driveway. The three went to the front door, which flew open, revealing several masked men, one of whom punched Ms Douglass, causing her to fall to the floor. While Wragg had accepted responsibility for attending the victim's home and smashing a window, he sought leave to appeal the assault part of his conviction, denying that he was the principal offender, and also denying that he was aware of what was happening within the home. The state had argued that the only reasonable inference open was that the appellant was the violent masked intruder or he was aiding that person. Wragg, who was 26 at the time of the conviction, sought leave to appeal, claiming the trial judge had erred in his directions to the jury on three occasions, including failing to adequately direct the jury that his culpability had to be established beyond reasonable doubt. But today, Justices Carmel McLure, Michael Buss and Robert Mazza rejected the appeal bid. "The proposed ground of appeal does not have a reasonable prospect of success," Justice Buss said. It is unarguable.
