He has a particular interest in the rights of protesters, and has represented protesters in criminal court, as well as assisting with judicial review and civil claims in protest cases.
Cian also has an interest in international matters or those with a cross-jurisdictional dimension. He has written about the challenges that recent decisions such as AB v. Secretary of State for Justice  UKSC 28 pose for human rights advocacy in the European Human Rights Law Review.
Cian acts on behalf of bereaved families in inquests touching on deaths in settings including prisons, in hospital, mental health custody, and in the community.
His recent instructions have included in inquests on behalf of the families of:
Jamie Lee Bennett, whose death in a bail hostel may have been prevented if there had been better support, leading to Prevention of Future Deaths reports to the Ministry of Justice, and to the company responsible for prison healthcare;
an individual who died while in the healthcare unit of a prison in relation to which the jury found neglect and extensive causative failings contributed to death;
an individual whose self-inflicted death in the community led the Coroner to make a Prevention of Future Deaths report to the Home Secretary;
Cian was led by Maya Sikand QC in the inquest into the death of Mark Culverhouse, who took his own life while unlawfully detained at HMP Woodhill. The jury found that a defect in the system of licence recall and release, as well as detention in the Segregation Unit, contributed to Mark's death.
He was led by Fiona Murphy in the inquest into the death of Shane Bryant, who died after a 17 minute long restraint by an off-duty police officer and members of the public. The jury found that unreasonable force, and missed opportunities, both contributed to the death.
Cian has particular expertise on the engagement of Article 2 ECHR and has given training on Article 2 and its role in inquests and related civil claims. He has also acted pro-bono under licence from Advocate, with support from INQUEST.
Cian offers advice and representation in relation to actions against public authorities, including the police, as well as prisons and local authorities. Recent instructions have included:
