Because of this connection of the two concepts, it is often argued that only Congress can declare martial law, because Congress alone is granted the power to suspend the writ. The President, however, is commander-in-chief of the military, and it has been argued that the President can take it upon himself to declare martial law. In these times, Congress may decide not to act, effectively accepting martial law by failing to stop it; Congress may agree to the declaration, putting the official stamp of approval on the declaration; or it can reject the President's imposition of martial law, which could set up a power struggle between the Congress and the Executive that only the Judiciary would be able to resolve.
