In litigation within the United Kingdom, the stage of "interim applications" is the part of the legal process that allows parties to seek specific, temporary, or interim orders from the court to manage and advance their case before the trial. These applications are designed to deal with various issues, such as procedural matters, case management, and substantive legal issues, ensuring the smooth progression of the litigation.

Key features of interim applications in UK litigation include:

1. Purpose and Necessity: Interim applications serve multiple purposes, including preserving evidence, protecting parties' rights, and streamlining the litigation process. They are often used when a party needs immediate relief or clarification on a specific issue.
2. Types of Interim Applications: These applications can take various forms, such as applications for injunctions (prohibiting or compelling certain actions), orders for disclosure of documents, security for costs, summary judgment, striking out claims, and more.
3. Procedure: Interim applications typically follow a prescribed procedure that involves filing an application notice specifying the relief sought and the legal basis for it. The opposing party has the opportunity to respond with evidence and legal arguments.
4. Evidence: The court may require parties to submit evidence, including witness statements or expert reports, to support their applications or defenses. This evidence helps the court make an informed decision.
5. Hearings: Many interim applications lead to a court hearing where both parties present their arguments and evidence. The judge then issues a ruling based on the merits of the case and the applicable law.
6. Urgency: Some interim applications are considered urgently due to their time-sensitive nature. In such cases, parties can apply for "without notice" or "ex parte" hearings, where they seek immediate relief from the court before notifying the opposing party. However, they must disclose all relevant information to the court, and the matter may be revisited at a later date with the other party's involvement.
7. Costs: In the UK, the court may order the losing party to pay the legal costs of the successful party in an interim application. Costs are an important consideration, as they can be substantial, and parties should be mindful of the potential financial implications.

Interim applications are a crucial tool in the litigation process, providing parties with the means to address pressing issues and secure temporary relief when necessary. Their efficient use can help streamline the legal proceedings, promote fairness, and ensure that the parties' rights are protected throughout the course of the litigation.
