Under section 10(1)(c) of ESTA, an eviction requires proof of two conjunctive elements: (1) a fundamental breach that damages the foundation of the owner-occupier relationship; and (2) that the breach cannot be reasonably and practicably restored. A single instance of alcohol-related misconduct, even resulting in dismissal, does not necessarily constitute a fundamental breach sufficient to warrant eviction. Under section 10(3) of ESTA, the subsections are peremptory and conjunctive. To satisfy section 10(3)(c), a land owner must produce concrete evidence demonstrating 'serious prejudice' to their business operations, establishing both the existence and degree of prejudice with a causal connection to the occupier's continued presence. Bare assertions of hindrance to efficiency or material prejudice, unsupported by factual evidence, are insufficient. ESTA, as protective legislation giving effect to constitutional rights in sections 25(6) and 26(1), must be construed strictly in favor of occupiers, and land owners bear the onus of establishing all statutory requirements for eviction.
