The binding legal principles established are: (1) The High Court lacks jurisdiction to entertain a rei vindicatio claim for property allocated under an employment contract where the employment relationship remains disputed and labour proceedings are pending to determine that status; (2) A rei vindicatio application is premature when filed before the underlying labour dispute regarding the employment contract has been conclusively determined; (3) The defence of res judicata applies where a prior court has adjudicated an identical claim between the same parties concerning the same subject matter founded on the same cause, and that order remains extant without being reviewed or appealed; (4) Material non-disclosure of prior court proceedings, particularly unfavorable ones, by an applicant in its founding affidavit justifies dismissal of the application; (5) A debtor-creditor retention lien over property is only available where the creditor has by contract performed work or incurred expenditure on that specific property, not merely because the debtor owes money generally; (6) An application stands or falls on its founding affidavit and deficiencies cannot be remedied through belated attachments to answering affidavits.
