The officer of nearly 40 years was the subject of a special sitting at the Dunedin District Court last week to mark more than two decades as a police prosecutor.
But his colleagues were keen to put him through the wringer before his retirement on Friday.
Rather than his normal spot at the front bench, Sgt Scouller was directed into the witness box - that alone providing some humour for the many lawyers, police officers and court staff in attendance.
Defence lawyer John Westgate addressed the hearing rubbing his hands together but the ex-prosecutor landed the first blow before the American could open his mouth.
``Can I get a new lawyer?'' Sgt Scouller asked.
Mr Westgate described the man as ``a contradiction''.
``He always had a firm handshake and loud hearty laugh,'' he said.
``Little did I realise, in court when on his feet arguing his case, all the bets were off.''
The pair had crossed swords many times over the decades and Mr Westgate was glad he had not kept score.
``I lost more than I won against him, there's no doubt about that,'' he said.
``Neither did he hold a grudge, nor did he gloat. He just got on with things.''
Defence lawyer Rhona Daysh added a little pizzazz to proceedings, removing her legal robes to reveal a little pink number.
She called it ``apres-dinner wear'' and added a fascinator for good measure before ripping into her speech.
Many of her comments about Sgt Scouller were as scandalous as her outfit but she finished simply with: ``we love you, we'll miss you''.
Crown prosecutor Robin Bates said the officer's tenure deserved recognition but he chose to focus on events that took place outside the courtroom.
At a local football match, a spectator collapsed on the touchline after suffering a heart attack.
It took an ambulance 40 minutes to find the ground and Sgt Scouller continued resuscitation efforts until medics arrived.
``You kept the spectator alive during that time and without question saved his life,'' Mr Bates said.
While in his role as a prosecutor, Sgt Scouller had outlasted numerous judges and changes in the law.
With some time on his hands, Mr Bates said it was a prime opportunity to get up to speed.
His gift to the sergeant?
``A super-duper copy of the Criminal Procedure Act.''
Judge John Macdonald called Sgt Scouller one of the best police prosecutors to appear before him in his 27 years on the bench.
The man himself, it seemed, was lost for words.
``It's been a hoot,'' he said.
