Case Summary:

Title: Mannai Inv. Co Ltd v Eagle Star Life Assurance Co Ltd (1997) 

Business premises, fixed term leases.  Notices required by lease to determine on third anniversary of commencement date. Notices given by tenant.  Notice technically incorrect.  Court finding in tenant's favour.

V. Important case with regard to notices.

FACTS: The Landlord, Eagle Star, owned office premises in London which they leased to Mannai Investment Co Ltd.  The lease contained a break clause which allowed the landlord to break the lease by serving 'not less than six months notice in writing .. such notice to expire on the 3rd anniversary of the term commencement date'. 
The tenant gave notice to terminate the lease by serving two idential break notices.  The notices were correct save that the termination date of the leases were stated as 12 January 1995 rather than 13 January 1995.  In this case, the [break] clause did not require the tenant to use any particular form of words.  He was simply required to use words which ambiguously convey a particular meaning, namely an intention to terminate the lease on January 13th.

HELD: The House of Lords concluded that the key test is whether the notice construed against its contextual setting would unambiguously inform a reasonable recipient how and when it was to operate.  If so, despite the error in the notice, termination should take effect.  The House of Lords rules that it was obvious to a reasonable recipient with knowledge of the leases and the third anniversary date, that the tenant wished to determine the leases on that date.  A reasonable recipient would not have been perplexed by the minor error in the notices.

The following principles were derived from the case:-

1.  notices exercising break clauses will be valid even if they contain errors if they are sufficiently clear & unambiguous to leave a reasonable recipient in no reasonble doubt as how & when they operate;the test is an objective one;

2.  evidence of what the landlord knew is inadmissable but publically available information is admissable;

3.  but a notice can be so unambiguously wrong that it cannot be saved by any construction.
