The binding legal principles established are: (1) Where a court has set aside the withdrawal of an offer letter and declared it valid and effectual, the land authority cannot validly issue a lease over the same land to another party without addressing the subsisting offer letter; (2) The three requirements for an interdict under Setlogelo v Setlogelo 1914 AD 221 must all be satisfied: a clear right (as a matter of evidence), reasonable apprehension of injury, and absence of alternative remedy; (3) A rights holder cannot be barred from protecting his rights when he was not made aware of or party to processes that threaten those rights; (4) A matter is urgent where the applicant acts immediately upon becoming aware of threats to his rights, regardless of whether information was publicly available if there is no proof the applicant was actually aware; (5) Interim and final relief are not impermissibly similar where they relate to different pending matters with different purposes; (6) Registration of competing rights does not render an application overtaken by events where the registration occurred without notice to an existing rights holder with a valid court-confirmed claim.
