A police officer sacked for allegedly "dogging" while on duty is to appeal to the Home Office to be reinstated.
Police say the case was "robustly investigated"
Darren Lumber, 35, was sacked from his post as a beat manager over claims he joined in with a man and woman as they had sex at Sand Point, North Somerset.
If the Home Office's police appeal tribunal decides that Avon and Somerset police's investigation was inadequate, Mr Lumber could return to work.
A police spokesman said the outcome was "justified and appropriate."
He added: "Chief Constable Colin Port had carried out a review of the case which concluded the hearing was conducted fairly."
Mr Lumber's alleged behaviour was branded "disgraceful" by a senior officer and he was dismissed on the grounds of misconduct while on duty after a disciplinary hearing.
The former officer was not available for comment on Monday but in a statement said: "I have strongly denied this allegation from the start and have the full support of my family and close friends."
A Home Office spokesman said it would not comment on individual cases
But he added any such case would go before the police appeals' tribunal appointed by the local authority in question.
Mr Lumber had worked as a beat manager in Kewstoke, near Weston-super-Mare. He was investigated after a fellow member of staff became concerned about his behaviour.
Dogging is the name given to the practice of having sex with strangers in public places.
