Wallace v HMRC

Harriet Brown recently acted for the taxpayer in Wallace v HMRC. The taxpayer had brought a claim against HMRC to recover amounts wrongly paid to HMRC under a mistake of law. HMRC applied to strike out the taxpayer’s claim on the basis that since the introduction of the Taxes Management Act 1970, Schedule 1AB the statute included express words to that effect, that a common law claim was not available to the taxpayer. The judgment can be found here.

Scotch Whisky Association v. The Lord Advocate [2017] UKSC 76.

Philip Simpson, Q.C., of Old Square Tax Chambers, successfully represented the Advocate General in a Supreme Court challenge by the Scotch Whisky Association (SWA) to the Scottish Government’s Alcohol (Minimum Pricing) (Scotland) Act 2012.  The appellants presented a petition for judicial review challenging the lawfulness of the Act and arguing that minimum unit pricing was disproportionate under EU law, breached world trade law, and breached the Treaty and Act of Union by which England and Scotland united in 1707. The factual basis of the challenge was, in summary, that the same effect could be achieved by increasing excise duties, whether alone or in combination with other measures.
