In other chapters, we examined how party autonomy shapes the parties’ contractual relations. Indeed, party autonomy is the cornerstone of the law of contracts and in general terms, the law intervenes in this process only sparingly with mandatory rules. In this chapter, we examine those circumstances where the civil law (both the CC and special laws) not only intervenes but invalidates the parties’ express consent on the ground that their agreement lacked good faith or imposed unfair terms on the weaker party. The imposition of good faith is equally justified by reference to public policy even if not expressly spelt out. This ‘parental’ regulation of contracts is not without contention and as the reader will come to realize, the contours of the application of good faith differ among jurisdictions, although our emphasis here is on the Qatari experience.

This chapter subjects the revival of formal and classical law values in contract law to critical examination. The emergence of a commercially oriented contract law is explored across a number of contract developments over recent years: the reassertion of party autonomy and the emphasis on contract law as default rules; the return to a formalist style of contract interpretation; the marginalisation of equity and considerations of public policy in contract; the tendency of judges to uphold contract terms whose validity was previously regarded as questionable (‘no oral modification’ and ‘no reliance’ clauses); the dilution of common law controls on contract terms (in relation to penalties, for example).The first part of the chapter examines recent contract law developments that suggest the re-emergence of formalism in law. The second part explores the common law’s retreat from a role as general regulator of contracting activity in the context of an increasingly contractualised society.

The advent of the Australian Consumer Law (ACL) as a law having uniform application throughout Australia will have a significant impact upon some areas of contract law. Most notably, the ACL will impact upon statutory unconscionability, implied terms in the form of consumer guarantees, misleading or deceptive conduct (the statutory corollary to the common law doctrine of misrepresentation) and unfair contract terms. The last topic is the focus of this chapter: the unfair contract terms regime of the ACL, as provided for in ss 23–28, sets up a mechanism for determining whether terms in standard form consumer or small business contracts are unfair.
