Dr Taylor accepts instructions on fitness to plead across criminal proceedings, combining specialist forensic psychiatric practice with formal legal training. The focus of his work is the interface between a defendant’s clinical presentation and the legal test the court must apply – which is precisely where a fitness assessment succeeds or fails. More about him is at drnicholastaylor.me.

Who the site is for

It is written for practitioners who need precision: the barrister preparing a fitness argument, the solicitor deciding whether to seek a report, the expert refining their approach, and the student or researcher who wants the test set out rigorously rather than in summary.

The practice

Instructions are handled by Forensic Psychiatry Experts, Lion Court, Melbourne Road, Staunton Harold, Ashby-de-la-Zouch LE65 1RT. Assessments are undertaken by experienced consultant forensic psychiatrists across England and Wales. Details of the wider practice are at forensicpsychiatryexperts.co.uk, and how to make an enquiry is on the Contact page.

Disclaimer

This site provides general information about the law and is not legal advice. The law on fitness to plead is complex, fact-sensitive and expected to change. The case summaries are selective and should not be relied upon without reading the authorities in full. Anyone facing or involved in criminal proceedings should obtain advice tailored to their circumstances from a qualified lawyer and, where appropriate, a suitably qualified expert.
