The neglect of restitution in the Scottish legal canon has greatly disadvantaged practitioners in the jurisdiction - very few will therefore be able to ignore this book. It will also be an invaluable reference for English lawyers. W. J. Stewart has untangled the law and set it out in its full theoretical and principled structure, covering all the relevant case law along the way. This text makes an attempt to apply Professor Birks' analysis to Scots law identifying questions of enrichment and cases supporting ""unjust factors"". Such an analysis has now been applied in the first Division in Shilliday V. Smith. This title is supplied with a supplement published in 1995.
