A more thorough explanation:

Sharp practice refers to actions that someone takes that push the boundaries of rules or standards. In law, sharp practices are actions by lawyers that go against the accepted standards of practice, but they do not necessarily break an actual law.

• Overly pressuring witnesses
• Requesting documents from opposing parties during discovery
• Charging excessive fees
• Abusing loopholes

These examples illustrate how someone can use sharp practice to gain an advantage in a legal case. For example, a lawyer may pressure a witness to change their testimony or request irrelevant documents from the opposing party to waste their time and resources. While these actions may not be illegal, they are considered unethical and can lead to criticism or fines from a judge.

It is important to note that lawyers may use some sharp practices, but they must be careful not to use them too frequently or face sanctions and harm to their reputation.
