Mulcahy v Hoyne [1925] HCA 17

Mulcahy v Hoyne [1925] HCA 17

Knowledge and acquiescence by a lessor in the lessee's unlawful trading constitutes neither a binding waiver of covenant nor estoppel sufficient to prevent the lessor from determining the lease for breaches, especially where such waiver lacks consideration and is against public policy to approve or encourage illegality. Acceptance of rent with knowledge of past breaches prevents relying on those breaches, but does not bar determination for subsequent breaches committed after receipt of rent.

Procedural Posture

Appeal / High Court of Australia on Appeal From Supreme Court of Victoria

Legal Issues

  1. 1 Whether the lessor waived the right to forfeit the lease for breaches of covenant through knowledge and acquiescence in the breaches
  2. 2 Whether the lessor is estopped from relying on breaches of covenant to determine the lease
  3. 3 Whether a parol waiver or estoppel can arise from knowledge and acquiescence in breaches involving unlawful acts under licensing law

Ratio Decidendi

Knowledge and acquiescence by a lessor in the lessee's unlawful trading constitutes neither a binding waiver of covenant nor estoppel sufficient to prevent the lessor from determining the lease for breaches, especially where such waiver lacks consideration and is against public policy to approve or encourage illegality. Acceptance of rent with knowledge of past breaches prevents relying on those breaches, but does not bar determination for subsequent breaches committed after receipt of rent.
