Supreme Court
The Supreme Court ruled that Littlewoods was not entitled to compound interest on a historic VAT overpayment, only the simple interest provided for under the statutory VAT regime. The Court held that the Value Added Tax Act 1994 provided a complete and exhaustive code for interest, which precluded any separate common law claim for compound interest based on unjust enrichment.
