A more thorough explanation:

Summary adjudication is a legal process that allows a court to decide on the merits of a specific issue or claim before a trial. It is a pre-trial procedure that can be initiated by either party through a motion. The purpose of summary adjudication is to reduce the cost and length of litigation by resolving selected issues, leaving the remaining ones to be settled at trial.

For example, in a breach of contract case, summary adjudication can be used to determine whether there was a breach of contract or not. If the court finds that there was no breach of contract, then the case may be dismissed. However, if the court finds that there was a breach of contract, then the issue of damages may still need to be determined at trial.

It is important to note that summary adjudication can only be granted if it completely disposes of a cause of action, an affirmative defense, a claim for damages, or an issue of duty. This means that all elements of a cause of action must be proven or denied for summary adjudication to be granted.

Summary adjudication is commonly used in California's civil procedure, and the statutes that govern motions for summary adjudication state that a motion for summary judgment shall be granted only if it completely disposes of a cause of action, an affirmative defense, a claim for damages, or an issue of duty.

Overall, summary adjudication is a useful tool for parties to resolve specific issues or claims before a trial, which can save time and money in the litigation process.
