The use of legislative history by the courts as an aid to the construction and interpretation of statutory provisions has an extensive common law history. This has encompassed significant variation in judicial approach, perhaps reflecting changing constitutional relationships. Where principles have emerged they have been somewhat inconsistently applied, no doubt because courts have a residual competence to regulate their own procedure which is only loosely regulated by superior courts.

Traditionally, common lawyers are used to examining other jurisdictions of their legal family as a source of inspiration for law reform or even as persuasive authority for the development of case law. Developments in continental civil law jurisdictions are less noted. However, particularly in the field of public law, English law is now being influenced by civil law concepts through the mediation of Community law.1 Product liability provides an example in private law of rules shared by the civil and common law jurisdictions of the European Union due to harmonisation by the Product Liability Directive. An important new area of non-contractual liability is environmental liability. Firmly established in the United States, liability for damage to the environment is increasingly being introduced in many countries around the world.3 In the European Union, the first step towards Community-wide legislation was taken in March 1993 with the publication of a Green Paper by the Commission.4 One of the many controversial aspects of a possible environmental liability regime is the issue of standing to sue.
