Tax analysis: In Burlington, the Upper Tribunal (UT) dismissed HMRC's appeal, finding that the First-tier Tax Tribunal (FTT) was entitled to come to the decision that the anti-abuse provision (employing a main purpose test) in the UK-Ireland double tax treaty (DTT) did not apply. Although Burlington, an Irish tax resident company, had purchased the debt claim from the liquidators of SICL (a Cayman Islands company which did not benefit from any exemption from UK withholding tax), the FTT had not made an error of law in deciding that neither party had a main purpose of taking advantage of the withholding tax exemption provided by the UK-Ireland DTT. Consequently, Burlington benefited from the exemption in the DTT and was entitled to a repayment of the UK income tax withheld from the payment of UK source yearly interest made by Lehman Brothers International (Europe) (LBIE), a UK tax resident company.
