 The golden rule of interpretation, together with the principles reflected in "Delmas", has in recent years endured much criticism.The trend, in recognition of this, has been to erode the influence of the parol-evidence rule, admitting rather more kinds of evidence than fewer, although the practice of allowing all evidence has been also been criticised.No court, yet, has gone so far as to overturn "Delmas"—judges usually confine their disapproval to "obiter dicta"—but it remains the case that the rules of interpretation in the South African law of contract are themselves hard to interpret, so that it falls to the particular views of each individual judge.
