Calla Randall has a broad practice in criminal, extradition, public and regulatory law.
Her recent cases in general crime include:
In public law, Calla represented West Yorkshire Police in a lengthy inquest into the death of a student police officer (led by Hugh Davies KC). The Coroner found that WYP had not caused or contributed to the death. Calla is currently instructed in the Independent Inquiry into Grooming Gangs on behalf of West Yorkshire Police (led by Hugh Davies KC). Calla is also currently defending the Metropolitan Police Service in a claim of misfeasance in public office which involves complex jurisdictional and human rights issues (led by Nicholas Yeo KC).
In extradition law, Calla has considerable experience acting for Part 1 countries throughout proceedings – from initial hearings in the Magistrates’ Court to renewal hearings in the High Court. She has frequently dealt with a wide variety of expert evidence and complicated Article 3 challenges involving country-wide thematic issues. She has also represented Part 2 countries in CMHs and bail applications in the High Court.
Calla defends and prosecutes as a led junior and as sole counsel. Her current and recent instructions cover the spectrum of serious crime, including GBH, drug dealing, serious sexual offences, and possession of offensive weapons (all as sole counsel).
Calla has experience dealing with vulnerable defendants and witnesses. She has made representations on fitness to plead, worked with intermediaries, and cross-examined vulnerable witnesses following ‘ground rules hearings’ (including a five-year-old child who allegedly witnessed her father being assaulted).
Calla also has an advisory practice encompassing appeals against conviction and sentence and applications for quasi-criminal orders.
Secured the acquittal of a police officer accused of GBH after conducting unnecessary CPR on a member of the public. The Crown offered no evidence after representations were made arguing that Cunningham recklessness could not be proved on the prosecution case.
Represented a police officer accused of corrupt/improper use of police powers and two counts of ABH. The Crown offered no evidence after service of the defence statement, which raised a defence of automatism following a suspected spiking of the defendant’s drink. A toxicologist and psychiatrist were instructed.
Represented a man accused of intentional strangulation of his ex-partner. The defendant was acquitted.
Represented a man with a positive NRM referral identifying him as a victim of modern slavery who was accused of four offences of Class A PWITS. The Crown offered no evidence after representations were made arguing that it was not in the public interest to prosecute.
Secured the acquittal of a police officer accused of assaulting a more senior police officer within his force. The alleged victim’s five-year old daughter was a witness to the incident and was cross-examined at the trial.
Calla represents both Judicial Authorities and Requested Persons in extradition proceedings. She accepts instructions in Part 1 and Part 2 cases. Calla has extensive experience dealing with cases both at first instance in Westminster Magistrates’ Court and in the Administrative Court on appeal.
Calla completed an eight-month secondment at the CPS Extradition Unit in February 2026.
Represented the Requesting State in a multi-handed extradition hearing which involved a significant quantity of medical evidence. The extradition of both Requested Persons was ordered.
Represented the Requesting State at a renewal hearing in the High Court. The case involved two expert psychiatric reports and a significant quantity of medical evidence. The Applicant served a last-minute application to admit fresh evidence which was successfully opposed applying the Fenyvesi criteria. The appeal was dismissed.
Represented the Requesting State in an extradition hearing involving section 2, 10, and 20 issues. The Requested Person’s extradition was ordered.
Calla practises across multiple areas of public law.
Calla has represented the Metropolitan Police Service and West Yorkshire Police in multiple inquests. This has frequently involved drafting complex submissions on the applicability of Article 2, and issues of scope and disclosure.
Calla is currently instructed by West Yorkshire Police in the Independent Inquiry into Grooming Gangs (led by Hugh Davies KC).
Calla has also assisted other members of Chambers in a range of judicial reviews, including in the case of Watson, a seminal JR in the field of police misconduct where the court determined that police misconduct proceedings could not be brought in relation to pre-attestation conduct.
Instructed on behalf of West Yorkshire Police.
Represented West Yorkshire Police in an inquest involving the death of a student police officer. The Coroner found that WYP had not caused or contributed to the death.
Calla is regularly instructed in a wide range of professional discipline contexts including cases involving police misconduct, police vetting (under the new regulations), architectural misconduct, and the Teaching Regulation Agency (TRA).
Represented a police officer accused of assaulting a member of the public while off duty. The panel accepted that it was a one-off incident, and the officer received a final written warning.
Representing a police officer accused of engaging in inappropriate conduct online. Substantial arguments are being run about the Officer’s Article 8 right to a private life, and the lack of specificity in the allegations (applying the principles in Wingate). The case is currently before the Police Appeals Tribunal.
Representing the Architects Regulation Board in relation to a registrant accused of failing to carry out work for his clients diligently. The panel found the facts proved and found that the facts amounted to unacceptable professional conduct. The decision on sanction is pending.
Represented the Teaching Regulation Agency in relation to a teacher accused of serious sexual assaults involving four children. Almost all the facts were found proved, and the Teacher was prohibited from the working within the teaching profession.
Calla is regularly instructed in a wide range of civil and quasi-criminal matters.
Calla has acted for multiple police forces in civil actions against the police involving claims of misuse of police powers and breaches of human rights.
Calla is also instructed in civil investigations. She was recently instructed by a national newspaper to conduct an internal investigation into allegations of sexual assault and rape made against one of its employees, after the police determined that there was insufficient evidence to bring a criminal prosecution. Calla was led by Amanda Pinto KC.
Calla is regularly instructed by the Metropolitan Police Service to advise on and appear in applications for the full range of Civil Preventative Orders, in particular sexual risk orders, sexual harm prevention orders, and stalking protection orders. Calla also has considerable experience dealing with gang injunctions which involve sensitive evidence and ex parte applications in the County Court and Youth Court, alongside related contempt of court proceedings. Calla also appears for defendants facing applications for civil orders. She recently successfully resisted an application for an interim SRO on the basis that the defendant (a teacher accused of serious sexual offences against underage students) was already subject to restrictive bail conditions.
Calla has also assisted the Metropolitan Police Service in drafting production orders, most notably in a case involving the prosecution of an alleged war criminal.
