220. Notice given by one of several joint owners or joint tenants.

In the case of a periodic tenancy, such as a tenancy from year to year, a notice given by one of several joint owners is effective to determine the tenancy because the tenant enjoys the whole of the property only so long as he and all the landlords concur. Likewise a notice by one of several joint tenants will terminate a periodic tenancy1. Personal representatives are joint tenants, and one of them may give an effective notice2. Where, however, a lease is determinable under an express power contained in the lease for determination by 'the landlords', the lease may
