What must occur for a party to be able to appeal an interlocutory order denying an injunction?

In California, a party has the right to appeal an interlocutory order denying an injunction immediately, without needing to wait for a final judgment in the case. This is significant because interlocutory orders can have substantial effects on the rights and obligations of the parties involved, particularly when an injunction is sought to prevent harm or enforce rights during the litigation process.

Immediate appeals for such orders are allowed to ensure that the party seeking the injunction can address the issues at hand without unnecessary delays that could lead to irreparable harm. Therefore, the correct answer reflects the procedural ability for a party to appeal at this stage rather than being required to wait for a final resolution of the case or fulfill additional prerequisites like seeking permission from the court.

In contrast, other options present conditions that relate to aspects of the appellate process that do not apply to immediate appeals of interlocutory orders denying injunctions. For instance, the requirement for a final judgment pertains to appeals from final orders, while the timeline for appealing within 30 days applies to certain other types of decisions, but not specifically to the immediate appeal of an interlocutory order.
