This book examines an area of personal injuries law that has been largely neglected by other writers, but which is of vital importance in practical terms when establishing quantum of damages for personal injuries. It provides detailed coverage of the law as it works in practice, but also important insights into the underlying legal principles and policy. There is comprehensive analysis of the rules relating to the deduction of social security benefits, including the Social Security (Recovery of Benefits) Act 1997 and the new rules concerning recovery of NHS costs from insurers. The book also explains in detail how the deduction of private insurance payments, gifts and charitable payments, benefits relating to employment, benefits related to the cost of care, and benefits accruing to dependants all impact upon the awards made by the Courts.
