A more thorough explanation:

Definition: In English law, drop refers to a rule nisi that is not adopted because the members of a court are equally divided on the issue. The rule is dropped rather than discharged or made absolute.

Example: If a court is divided on a particular issue, and the judges cannot come to a unanimous decision, the rule nisi is dropped. This means that the rule is not adopted, and the case may be dismissed or retried.

Explanation: The example illustrates how the term "drop" is used in English law. When a court is equally divided on an issue, the rule nisi is not adopted, and the case may be dismissed or retried. This is known as dropping the rule, and it is a common practice in English law.

Additional Example: A company may set a drop-dead date for a project, which is the date by which performance is required as a condition. For example, if a company is working on a new product launch, they may set a drop-dead date for the launch, which is the date by which the product must be ready for release. If the product is not ready by the drop-dead date, the launch may be delayed or canceled.

Explanation: The additional example illustrates how the term "drop-dead date" is used in business. A drop-dead date is a deadline that must be met, or there may be consequences such as delays or cancellations. This is a common practice in business, and it is important to meet drop-dead dates to ensure the success of a project or product launch.
