In 2009, he argued two expedited trials in the Commercial Court concerning the Boskalis vessel “WD Fairway”, a case which raised questions of abandonment and subrogation in the context of a CTL, as well as issues under section 423 of the Insolvency Act 1986. A third trial in 2010, involving the same vessel, raising questions in relation to an assured’s entitlement to interest on the CTL, was settled during final speeches.
