A more thorough explanation:

Triplicatio (trip-li-kay-shee-oh) is a Latin term used in Roman law. It refers to a defendant's response to a plaintiff's claim, in which the defendant denies the plaintiff's allegations and provides three different reasons or arguments to support their denial.

For example, if a plaintiff sues a defendant for breach of contract, the defendant may respond with a triplicatio by denying the breach and providing three different reasons why they did not breach the contract. These reasons could include a lack of evidence, a misunderstanding of the terms, or a legitimate excuse for non-performance.

Another example could be in a criminal case, where the defendant is accused of a crime. The defendant may respond with a triplicatio by denying the charges and providing three different reasons why they are innocent. These reasons could include an alibi, mistaken identity, or lack of intent.

The examples illustrate how a triplicatio works in practice. It is a legal strategy used by defendants to challenge the plaintiff's claims and provide multiple reasons why they are not liable or guilty. By providing three different arguments, the defendant can strengthen their case and make it more difficult for the plaintiff to prove their case. This legal tactic is still used today in some legal systems, although it is not as common as it was in Roman law.
