Privity of Contract: The Impact of the Contracts (Right of Third Parties) Act 1999 [PDF ebook] 

Privity of Contract offers a unique perspective of how the Contracts (Rights of Third Parties) Act 1999 works in practice. Issues covered include: the operation of the doctrine of privity prior to its repeal; the scope and impact of the 1999 Act; and the operation of the 1999 Act in the most important commercial contexts to which it is applicable. It also incorporates discussion and the text of the Law Commission reports, whose proposals produced the bill that ultimately passed into law.
