1. For a successful spoliation application, the applicant must prove: (a) peaceful and undisturbed possession (or quasi-possession) of the property, and (b) unlawful deprivation of that possession by the respondent. 2. A spoliation remedy is available to any despoiled person who exercises physical control over property to derive some benefit from it. Possession suffices if the holding is to secure some benefit. 3. Wrongful deprivation includes any deprivation against a person's will without legal process, amounting to taking the law into one's own hands. Whether the respondent had a stronger right or claim to possess is entirely irrelevant. 4. The defences available in spoliation proceedings are limited to: denial, impossibility of restoration, and counter-spoliation. 5. A contractual lien cannot justify self-help retention of property where the underlying contract has been cancelled by the party asserting the lien.
