    Significant Cases

    Appearing as sole counsel for the respondent in Singh v Dass [2019] EWCA Civ 360. Aidan successfully represented the respondent on appeal before McCombe, Moylan and Haddon-Cave LJJ. The case concerned a long-running building dispute where the respondent had won at a trial of a preliminary issue on limitation and the appellant sought to introduce a new argument on appeal based on s.29(5) of the Limitation Act 1980. Aidan successfully argued that it was not and should not be open to the appellant to raise a new argument at this late stage which was not supported by the findings made at trial.

    Representing Kirklees Borough Council in relation to a business rates avoidance scheme. Aidan successfully represented the local authority in a business rates dispute where the landlord claimed to have granted a lease of an office building to a newly-formed company that in turn claimed to be exempt from business rates because it was engaged in snail farming on the basis of a number of boxes of snails being placed in the building. The court held that the lease was not properly executed and was a sham. The judge found that the tenant “manifestly does not operate a snail farm any more than putting matchbox toy cars on the floor of the Property would constitute the operation of a car sales business”.
