A more thorough explanation:

A speedy remedy is a legal or equitable relief that can be pursued quickly before the aggrieved party suffers significant harm. It is an informal expression with no fixed meaning, and what is considered speedy in one context may not be considered speedy in other contexts.

For example, the Federal Tax Injunction Act requires a "plain, speedy, and efficient remedy" in state courts. However, the Act does not require preliminary or injunctive relief or even interest for delay.

Another example of a speedy remedy is a temporary restraining order, which is a provisional remedy awarded before judgment and pending the action's disposition. It is intended to maintain the status quo by protecting a person's safety or preserving property.

Overall, a speedy remedy is a legal or equitable relief that can be pursued quickly to prevent or redress a wrong before significant harm occurs.
