Jack Horlock



Jack is an Associate based in our London office and specialises in acting for police forces. Jack uses his enviable breadth of experience to provide comprehensive legal services to police forces with particular a focus on commercial and governance, collaboration, police powers, and general advisory work.

Drawing on his previous experience working in-house for police forces and health services, as well as his time as a Senior Crown Prosecutor, Jack’s advice is rooted in the reality of modern policing. He is motivated by helping his clients achieve their objectives, improve their services and response and Jack is always cognisant of the real-world policing context. Jack works with police forces and police and crime commissioners from the early stages of projects, including collaboration, and advises as to governance structures, liabilities issues and funding principles to ensure that each project is fit for purpose. Jack regularly drafts detailed, entirely bespoke agreements that are tailored specifically to his client’s project’s needs.  

Jack is particularly adept in dealing with instructions that cross into the political sphere. Recent instructions have seen Jack prepare advice on clients’ responses to central government consultations — and to prepare the draft response itself. Additionally, Jack advises on potential disputes that stand to be referred to government ministers for resolution, including both merit- and procedure-based advice.

Jack also works with police forces to help them improve their use of protective tools to keep people safe, particularly in the context of violence against women and girls. He has worked with police forces to implement new, and streamline existing, processes for things like Domestic Violence Protection Orders, Stalking Protection Orders, Sexual Risk Orders and Anti-Social Behaviour Injunctions. Part and parcel of that work is providing bespoke training to officers both in-person (to small groups and larger, lecture-style training), and remotely.

Jack is part of our internal advocacy unit and regularly represents police forces in the Magistrates’ and County Court, as well as representing the Appropriate Authority in presenting police misconduct cases to misconduct panels in full hearings, and Chief Officers in accelerated hearings.
