## Facts

- Mr. Lonsdale (landlord) and Mr. Walsh (tenant) agreed on a seven-year lease of a mill.
- The agreement specified that rent was to be paid quarterly in arrears, but a year's rent could be demanded in advance by the landlord.
- No formal deed of lease was executed, but Mr. Walsh took possession and paid rent quarterly in arrears.
- Mr. Lonsdale later demanded a year's rent in advance, relying on the agreement's terms.
- Mr. Walsh disputed the demand, arguing that without a deed, the agreement could not be enforced as a lease at law and that he occupied only as a periodic tenant.
- The dispute centered on whether the executory agreement without a deed created any enforceable leasehold interest.

## Issues

1. Whether an executory agreement for a lease, lacking a formal deed, can be enforced as an equitable lease.
2. Whether the terms of the executory agreement, specifically the advance rent provision, are enforceable absent legal formalities.
3. How the conflict between common law requirements for leases and equitable principles should be resolved following the Judicature Acts 1873-1875.

## Decision

- The Court of Appeal held that the landlord, Mr. Lonsdale, was entitled to enforce the terms of the executory agreement, including the right to demand a year's rent in advance.
- The court stated that equity treats as done that which ought to be done, so a valid agreement for a lease is regarded as if the lease had been actually granted.
- It was determined that the tenant held the premises on the same terms as if a formal legal lease had been executed.
- The court confirmed that after the Judicature Acts, equitable rules would prevail over conflicting rules of common law.

## Legal Principles

- A valid agreement for a lease, even if not executed by deed, creates an equitable lease enforceable by the courts.
- The doctrine "Equity looks on as done that which ought to be done" applies, treating executory agreements as if performed.
- Following the Judicature Acts, where common law and equity conflict, equity prevails.
- An equitable lease confers similar rights and remedies (such as specific performance and distress) as a legal lease, provided the agreement is valid.

## Conclusion

Walsh v Lonsdale established that an agreement for a lease, although lacking a deed, is enforceable in equity as an equitable lease. The case affirms the supremacy of equitable principles over common law technicalities in property agreements, ensuring parties are bound by their valid agreements and reflecting the merger of law and equity after the Judicature Acts.
