"It must be clearly understood and accepted that Guides/Interpreters are engaged on a casual, part-time, day-to-day basis, and that there is no guarantee of continuity of employment or income."
"It is entirely in the discretion of the Court to grant or refuse an extension of time. It may, for example, be granted where the omission to appeal in due time was due to a mistake on the part of a legal adviser. The fact that the Court of Appeal has in a subsequent case taken a different view of the law from that of the court below is not of itself a sufficient ground for an extension of time for appealing, but the circumstances as a whole may justify it."
"... The general rule is that, if a court of competent jurisdiction has reached a final and conclusive decision on the merits of a case, it is against public policy to allow it to be reopened (save on an appeal), even if that decision appears to be wrong in the light of the law as then understood or as subsequently evolved and clarified by judicial decision. The injustice and inconvenience which would flow from allowing relitigation usually outweigh the injustice of leaving even an erroneous decision undisturbed."
