Update on prosecution of 87-year-old William Brian Chorlton, accused of 11 offences relating to alleged raptor persecution in Lincolnshire

In April 2025, retired farmer William Brian Chorlton, aged 87, of Morkery Lane, Castle Bytham in Lincolnshire was summoned to court following reports that birds of prey were being poisoned in the Castle Bytham area.

He faced eleven charges relating to the unapproved or unlawful storage of the chemical Aldicarb, possession of a poisoners kit, and possession and use of four pole traps on his Pheasant shoot (see here).

Mr Chorlton appeared at Lincolnshire Magistrates’ Court in May 2025 and pleaded not guilty to all charges and the case was set to proceed to trial in October 2025.

However, at a pre-trial hearing in September 2025, Mr Chorlton’s lawyer submitted three separate legal arguments calling for the case to be dismissed. The District Judge rejected all three legal arguments and the application to dismiss the case was not upheld.

In a further pre-trial hearing a week later, and in a highly unusual move, Mr Chorlton’s lawyer announced that he intended to apply for a judicial review of the District Judge’s decision (see here), which meant that the original trial date of October 2025 was postponed until the judicial review application was heard.

A further case management hearing scheduled for January 2026 was also postponed as the application for judicial review was still underway (see here).

Since then, earlier this month Mr Chorlton’s application for judicial review was rejected by the High Court.

The rejection of the application for judicial review led to another case management hearing for the criminal case, and that took place this morning at Lincoln Magistrates Court in front of the same District Judge as before.

Mr Chorlton’s lawyer told the judge that, “You were right and we were wrong“, in relation to the judge’s earlier ruling that there were no grounds for the case to be dismissed. This means that Mr Chorlton’s defence team is not intending to challenge the High Court decision to reject the application for judicial review so the criminal prosecution is now back on track.

The defence stated that it would now instruct an expert witness and a new trial date has been set for October 2026. A further case management hearing will take place in July 2026, to look at areas of agreement / disagreement between the expert witness reports.

The papers from the judicial review application (Mr Chorlton’s statement of facts of grounds and the Crown Prosecution Service’s grounds of resistance) make for a fascinating read but I won’t publish those until criminal proceedings have concluded at Lincoln Magistrates’ Court so as not to jeopardise the prosecution.
