The Act Part 6 – Tax Returns, Enquiries and Assessments Defence of unjustified enrichment Section 109 – Defence to certain claims for relief under section 107 or 108
150.This section provides that Revenue Scotland can reject a claim for relief on the basis that paying it would unjustly enrich the person making the claim. This would happen if the taxpayer was not the person who ultimately bore the cost of the tax. For example, for SLfT, while the tax is paid by the landfill site operator it is ultimately borne by those charged for depositing waste at the site.
