That a contract can be brought to an end by: performance; agreement; breach and frustration
Discharge - 1st way, Cutter v Powell
Held that if a contract requires entire performance and a party fails to perform the contract in its entirety, they are entitled to nothing from the other party under the contract.
Discharge - 1st way, Hoenig v Isaacs
If C had substantially performed the contract they were entitled to the contractually agreed price minus the cost of the defects
Discharge - 1st way, Bolton v Mahadeva

Discharge - 1st way, Ritchie v Atkinson
Where the contract is severable C is entitled to payment for the amount supplied
Discharge - 1st way, Sumpter v Hedges

Discharge - 1st way, Planche v Colburn
Held that C was entitled to recover money for the work completed, because D had prevented the performance
Discharge - 2nd way
Agreements can end a contract when they are bilateral (and both parties gain a new benefit) but unilateral agreements (where only one party gains a benefit) must be made under a seal to be enforceable
Discharge - 3rd way
Where a part fails to perform an obligation, performs an obligation defectively or indicates in advance that they will not be performing an agreed obligation under a contract.
Actual or anticipatory
Discharge - 3rd way, Frost v Knight and Avery v Bowden
C can sue for anticipatory breach of contract as soon as the other party indicates that they will not perform
Discharge - final way
A contract may be frustrated where there exists a change in circumstances, after the contract was made, which is not the fault of either of the parties, which renders the contract either impossible to perform or deprives the contract of its commercial purpose.
Discharge - final way
Where a contract is found to be frustrated, each party is discharged from future obligations under the contract and neither party may sue for breach.
