A Melbourne engineer who claims a colleague repeatedly farted near him and "thrusted his bum" at him has vowed to go to the High Court after losing his bullying case 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.

Mr Hingst applied to appeal the case, saying "flatulence was a form of bullying" and his ex-colleague Greg Short was a serial farter.

The Court of Appeal ruled against Mr Hingst on Friday, refusing to grant him leave to appeal and ordering him to pay the defendant's legal costs.
