Christopher Lockhart-Mummery QC

Call: 1971Silk: 1986

Practice Summary

Christopher Lockhart-Mummery was called to the Bar in 1971, took silk in 1986, and was Head of Chambers at 4 Breams Buildings from 1993. He was head of the merged Chambers from merger until 2003. He has been a Deputy High Court Judge (planning cases) and a Recorder.

Having had wide experience in planning, compulsory purchase and compensation, parliamentary, local government and related work both at inquiries and in the courts, he now specialises exclusively in a wide range of planning work, for the private and public sectors.

Christopher is listed as a leading silk in planning in Chambers & Partners and the Legal 500:

“A doyen of the Planning Bar whose submissions are always well received.” “He’s a really powerful planning lawyer who can get into the nuts and bolts of cases.” “He provides quick, commercial advice.” (Chambers & Partners 2021)

“His style is far less aggressive than many silks and is much more effective as a result. Most importantly, however, he has laser-like precision when it comes to framing a case. Christopher has the confidence to identify the one or two critical points that he thinks will achieve a win and to focus on them to the exclusion of the others. This shows a degree of confidence and ability that few of his competitors have.” (Chambers & Partners 2017)

“He is the voice of authority.” (Legal 500 2016)


Christopher has practised in planning and related fields throughout his career, exclusively so for some 25 years. He is a CEDR accredited Mediator and a Co-Mediator on the RICS Planning Mediation Panel. Christopher is a strong believer in the role that mediation can play in all aspects of planning–related disputes.

Neighbourhood Planning

Christopher has a particular interest and experience in neighbourhood planning. He is Chair of the RICS/RTPI/DCLG Working Party which has produced Guidance for neighbourhood plan examinations.
