Commercial and criminal disputes, and regulatory matters are Calvin’s areas of expertise. Before joining private practice, he was a Justices’ Law Clerk and Assistant Registrar in the Supreme Court of Singapore.
As lead counsel, Calvin has obtained a search order for one of the world’s largest ship owners, and defended a business owner in a corruption case involving novel points of law. In the latter case, the High Court commended his “detailed and well-researched submissions”.
His recent work has included acting a claim involving over US$2 billion worth of art – discharging a worldwide Mareva injunction and obtaining a stay of proceedings on the grounds of forum non conveniens. The latter was the first case by the Court of Appeal to consider the relevance of the Singapore International Commercial Court to the Spiliada test.
He also acted for the finance manager of a megachurch in one of Singapore’s longest-running criminal breach of trust cases, and for the successful party in a landmark Court of Appeal decision on the doctrine of abuse of process.
Calvin has taught Constitutional and Administrative Law at the National University of Singapore and the Singapore Management University. An article he co-authored in this area was cited with approval by the Court of Appeal.
