Restraint of trade clauses are usually contractual clauses that go too far in limiting competition on the market. Under the proper functioning of competition law it is the policy of the law to ensure that all traders are free to select with whom they contract.

Issues of contractual consideration will also be looked at by the court – for example the court will look into whether the party that has been restrained has been paid enough for that restraint.

The claimant will also need to prove on the balance of probabilities that the clause is protecting their legitimate interests.
