Protestor Injunctions

Landmark is the market leader when it comes to protestor injunctions, combining its unique Chambers-wide specialisms of property and human rights expertise.


Landmark is at the forefront of the developing law relating to protest injunctions against persons unknown.

Landmark’s barristers regularly appear in the Supreme Court, Court of Appeal, High Court and County Court in proceedings involving protestors. They act in all sectors, including the healthcare sector, the education sector, the energy and renewables sector, the construction sector, the security sector and in cases involving public bodies.

In an area of practice that is highly time-critical, Landmark barristers have significant experience of achieving results within very tight timescales, and also of understanding what must be done procedurally in order to ensure that any Order is robust against challenge. Chambers has significant experience of bringing urgent claims both out of hours and as urgent business in the High Court vacation.

One reason for Landmark’s success is its breadth of specialisms given both the property expertise and human rights expertise that is essential in this area of the law. A further reason is that barristers at Landmark have significant practical experience of all aspects of this work, from inception to potential committal proceedings, and a track record in providing creative and practical results.

Recent clients have included major private landowners (including the owners of many of the country’s most famous landmarks and infrastructure), energy companies, government agencies, local government, NHS trusts, and universities.

A number of Landmark’s barristers have been recognised in Chambers & Partners and Legal 500 for their strength in this area, and regularly give talks which focus on this subject.

The following are examples of high-profile and key cases in which members have been involved:
