Ognjen’s practice has an emphasis on commercial work, group litigation and jurisdictional disputes. He also focuses on product liability, particularly where it intersects with these areas of specialism.

Ognjen is ranked by Legal 500 as a Leading Junior (Band 2) in Group Litigation.  He is also ranked by Chambers and Partners as a Leader in the Field in Group Litigation and in Band 5 for Commercial Dispute Resolution.

Ognjen was instructed as junior counsel for the Claimants in the long-running Post Office Group Litigation. Arising from a scandal frequently described as “the most widespread miscarriage of justice in UK history”, Ognjen was part of the successful team that secured multiple judgments in its favour on important legal issues. These judgments have also been imperative in the overturning of more than 90 criminal convictions.

Ognjen is instructed in multiple group actions arising from ‘emissions’ claims against different vehicle manufacturers. Outside of a purely domestic context, he has been instructed in many cases that have been brought in the UK by groups of claimants from all over the world. These cases are often founded on alleged international mass torts, and include the landmark decisions of the Supreme Court in Lungowe v Vedanta and the Court of Appeal in AAA v Unilever.

In terms of his commercial work, he is currently instructed in Commercial Court litigation arising as a result of a BIT Arbitration Award made against the Czech Republic in the sum of c.£560m.
