Legal Definitions - prove

To prove something in a legal context means to successfully demonstrate or establish the truth or falsity of a particular claim, assertion, or fact using evidence, testimony, or logical reasoning. It involves presenting enough compelling information to convince a judge or jury that a disputed point is indeed accurate or inaccurate, according to the required legal standard.

• Example 1: In a criminal trial, the prosecution aims to prove that the defendant is guilty of the crime beyond a reasonable doubt. They might present DNA evidence found at the scene, eyewitness testimony identifying the defendant, and security camera footage showing the defendant's presence.

  Explanation: Here, the prosecution is actively working to establish the truth of their claim (the defendant's guilt) by gathering and presenting various forms of evidence to convince the jury.

• Example 2: A small business owner sues a supplier for delivering faulty materials, claiming a breach of contract. To win the case, the business owner must prove that the materials were indeed defective, that this defect violated the terms of their agreement, and that it caused financial losses to their business.

  Explanation: This illustrates a civil case where one party has the responsibility to establish the truth of their claims (defective materials, contract breach, and damages) through documents like the contract, inspection reports, and financial records.

• Example 3: During a hearing for a patent infringement claim, the company that holds the patent needs to prove that a competitor's new product uses technology that is identical or substantially similar to their patented invention without permission. They might present detailed technical drawings, expert witness testimony comparing the two technologies, and sales figures showing market impact.

  Explanation: In this scenario, the patent holder must provide concrete evidence and expert analysis to establish the truth of their assertion that infringement has occurred, thereby convincing the court of their claim.
