He has been instructed in private prosecutions both in this jurisdiction on behalf of a corporate entity and advising in relation to a fraud based prosecution in Cyprus. He has further advised in relation to international corruption and bribery matters and has advised extensively in relation to revenue fraud and alleged tax evasion schemes operating both in this jurisdiction and abroad.
Mark regularly advises and conducts hearings in relation to post conviction confiscation and asset recovery, most recently in relation to international corruption/bribery allegations.

Mark advises on judicial review matters arising from criminal litigation, most recently, on a judicial review challenge to investigating agency’s procedure for identifying legal professional privilege material.
