Mussadak is a commercially astute British barrister with over 20 years’ experience in litigation and advisory work across the UK and Gulf region.
Mussadak’s domestic practice focuses on industrial disease litigation, involving complex liability disputes, factual and evidential challenges, and difficult issues of causation. He is recognised for identifying key issues most likely to resonate with tribunals and judges, distilling complex legal, medical, and engineering evidence into clear and compelling arguments, and exercising consistently well-reasoned judgment.
Mussadak regularly appears in alternative dispute resolution, including round-table negotiations and joint-settlement meetings. He undertakes advisory and dispute-related work with a Gulf dimension, particularly in matters governed by English law. He is associated, in a non-practicing capacity, with Bait Al Qanoon, a boutique law firm in Oman, and visits the Sultanate regularly to provide knowledge transfer, professional development, and comparative legal training programs. He lectures state entities in the Gulf and multinational corporations on international best practices in governance, risk, and regulatory compliance.
As UK Lead of the Omani British Lawyers Association (OBLA), Mussadak promotes professional collaboration between the UK and Oman. He delivers webinars in partnership with the British Omani Society (BOS) and the cultural attaché of the Omani Embassy in London. He writes regular articles on legal developments in Oman for OBLA and the BOS.
Mussadak brings depth and authority to industrial disease litigation, particularly noise induced hearing loss (NIHL), across the steel, rail, coal mining and ship-building sectors. He is highly proficient in the interpretation of audiometry and the application of the CLB diagnostic and the LCB quantification guidelines. His practice involves complex medical issues, including asymmetry, lower-frequency loss, de minimis arguments, limitation and date of knowledge under the Limitation Act and the exercise of discretion under section 33. Trials regularly involve detailed and technical cross-examination of medical and acoustic experts, where mastery of the underlying science is essential.
A significant part of Mussadak’s practice is devoted to military claims, in which he is nationally recognised. He has acted for hundreds of former and serving military personnel from the British Army, Royal Navy, and Royal Air Force against the Ministry of Defence (MOD). He has particular expertise in Military Noise Induced Hearing Loss (M-NIHL) and is well versed in the Overseas Operations (Service Personnel and Veterans) Act, the scope of “overseas operations”, combat immunity, and evolving causation issues linked to contested diagnostic criteria in M-NIHL litigation.
Mussadak has substantial experience advising, litigating and mediating in claims for costs, often exceeding £1 million. His work spans detailed assessments, fixed costs disputes, solicitor-client costs issues, and applications for wasted and non-party costs orders. He is regularly instructed in cost management hearings (CCMCs) and appears in substantial costs litigation before the Senior Courts Costs Office at the Royal Courts of Justice.
Mussadak has a developing international practice, with a particular focus on Gulf-facing advisory work, regulatory compliance and institutional engagement. Living part-time in Oman, he is regularly involved in international matters concerning cross-border regulatory frameworks, governance and risk management, and works closely with state entities, international organisations, and multinational corporations.
