| Implied Tenancies | Dockrill v Cavanagh | The operation of s 127 | 
 Note: Agreements as to duration are only relevant to whether rent is paid by reference to an aliquot part of a year | 
 (Does this become a tenancy at sufferance?) | Can arise 
 Despite the common law position s 127(1) of the CA (applied to Torrens) provides by force of statute that: 
 From Dockrill – other things can be incorporated – e.g. lessee’s covenant to repair, but not anything inconsistent with one month’s notice (Kemp v Lumeah – breach converts to terminable on week’s notice) Moore v Dimond – “quarterly payment” is part compensation for a year’s hence it will be from year to year 
 Box v Atfield – but if there is a tenant remain in possession after a lease for a year expires and pays weekly, a year to year tenacy will be inferred Burnham v Carrol Musgrove Theatre – holding over after a periodic tenancy creates a presumption that the same periodic tenancy is inferred |

| Reversionary Leases | Leases to commence in the future are called reversionary leases

Note: Interressee termini (no interest until the lessee enters pursuant to the lease) does not apply under s 120A of the CA
