What is the value of case law on legal research​

In addition to the guidelines themselves, case law helps to inform our understanding of how the guidelines work in a particular jurisdiction.

Explanation:

anticipatory breach of contract

as the name suggests, an anticipatory breach is a breach of contract before the time of performance. so, if a promisor denies to perform his promise and signifies his unwillingness before the time for performance, then it is an anticipatory breach of contract.

and

actual breach of contract

while an anticipatory breach is before the time of performance, an actual breach of contract is on the scheduled time of performance of the contract. an actual breach of contract can be committed either.
