 The hierarchical nature of the exercise has also been criticised.While its rigid procedures may look good on paper, moving progressively, until a solution is found, through all the options available, in practice it is difficult to apply in court; indeed, the courts very rarely follow it, as it extends proceedings unnecessarily; instead the whole exercise is usually integrated, with counsel leading as much evidence as possible.There is, therefore, a clear disconnect between theory and practice in this area of the law, although judicial support has been expressed for a more liberal approach to interpretation.
