She advised prisoners on a wide range of prison law matters, including the merits of potential civil claims and judicial review claims, and assisted with legal advice clinics in prisons in London. Accordingly, Miriam is very familiar with the wide-ranging issues faced by prisoners during their time in custody and has experience of matters such as adjudications, categorisation reviews and the imposition of licence conditions and their respective means of challenge.

As a member of the Centre for Women’s Justice Legal Reference Panel, Miriam also provides advice and assistance on a pro bono basis to female victims of physical and sexual violence seeking to challenge decisions not to prosecute by the police or the CPS under the Victim’s Right to Review Scheme.

Miriam has been appointed to the CPS Specialist Proceeds of Crime Panel at Level 2.  She acts in confiscation proceedings, both when having dealt with the underlying criminal allegations and after trial. Miriam is well versed with the complexities of the legislation and practical requirements to ensure the best possible result for her clients.

Miriam also has experience of cases raising third party interests. She acted for an interested party under section 10A of POCA in contested confiscation proceedings where the alleged benefit was over £1 million and there were parallel property determinations and divorce proceedings in the Family Court. She has successfully applied to increase the available amount for confiscation where third party interests were raised for the first time in renewed proceedings.

Miriam is particularly interested in the intersection between public and criminal law and advises on challenging decisions of criminal courts and public bodies in the criminal justice system by way of judicial review. Miriam appeared as sole counsel before a Divisional Court in Mishra v Colchester Magistrates’ Court; Colquhoun v Stratford Magistrates’ Court [2017] EWHC 2869 (Admin), which clarified the law surrounding the 21-day time limit for applying to the magistrates’ court to state a case.
