TMT analysis: This case centres around the Court of Appeal’s interpretation of a software services agreement, specifically the wording around limitation of liability. In particular, the court considered three main questions for the purposes of calculating quantum—the amount to which the contractual liability cap should be applied; whether the liability cap should be applied after considering set-off, or before; and whether the cap covers contractual interest. The court held that the cap should be applied to the total liability owed by each party to the other, separately, and not to the amount of both parties’ liability added together. Secondly, the court clarified that the cap should be applied before making adjustments for set-off. Thirdly, interest did not fall within the cap on the basis of an express term of the agreement stating that interest is the sole and substantial remedy for late payment (and is therefore separate). On the basis of its conclusions above, the court determined that total liability amounted to €4.2m, and not €5m as the High Court had previously established.
