Notable Cases:
R v GS: Hamish represented the first defendant to be tried in the Crown Court for low value criminal damage following s.50 PCSC Act 2022 (damage to memorials) after ketchup was thrown at a statue in Parliament. Trial involved lengthy legal argument around Article 10/11 ECHR and lawful excuse. The jury unanimously acquitted both defendants.
R v ES: Successfully defended an animal rights activist charged with conspiracy to steal animals. They were charged following an investigation by counter terrorism police into a group linked with the Animal Liberation Front. The protestor was acquitted after five-week Crown Court trial involving extensive legal argument on law of conspiracy.
R v SS: Secured acquittal for a protestor who caused significant damage to the building of a company which supplied the cladding used on Grenfell Tower and which manufactures parts for warplanes used by the Israeli military. The protestor was acquitted of Criminal Damage on the basis that he had a lawful excuse, acted to protect property and/or in necessity to save lives.
Insulate Britain: Instructed to defend in several public nuisance and highway obstruction trials arising from Insulate Britain’s 2021 protests on the M25 and City of London. Recent acquittal in R v Carter & others (published) following a successful argument to exclude evidence from National Highways.
Extinction Rebellion: Acted for numerous XR protestors in trials for obstruction of the highway, aggravated trespass and failing to comply with conditions under the Public Order Act.

R v CF: Secured acquittal following six-day jury trial for two counts of assault of an emergency worker (police officers) at a protest during covid restrictions. Forensic cross-examination showed officers to have exaggerated or lied about the assaults.
R v SA: Acted for defendant facing contempt of court proceedings related to conduct during an Insulate Britain trial at Inner London Crown Court. Hamish successfully persuaded the judge to impose no sanction.

Camp Beagle 5: Single counsel for all five defendants charged under s.14 Public Order Act, secured acquittals having successfully argued that the policing of the protest was itself unlawful, thus rendering the conditions imposed unenforceable.
HS2 (Wendover Tunnels 5): Effective plea in mitigation secured conditional discharges following guilty pleas to aggravated trespass arising from an HS2 ‘tunnelling’ protest which caused an estimated £3m loss to HS2 and two-month delay to construction work.
