A Melbourne engineer who claims his colleague repeatedly farted nearby and “thrusted his bum” at him, is hoping his bullying claim is successful on appeal.

David Hingst, 56, had sought $1.8 million in a suit against his former employer Construction Engineering, but a judge blasted the case out of the Supreme Court last year, finding there was no bullying.

Mr Hingst’s appeal came before the Court of Appeal on Monday, when he said “flatulence was a form of bullying”, and his ex-colleague Greg Short was a serial farter.
