The president commissions and promotes officers and decides on activating reservists for extraordinary service and on the mobilisation of the Defence Forces. If Parliament is not in session when a decision to mobilise is taken, it must be immediately convened. Declarations of a state of emergency (, literally, "state of preparedness") and state of war (, lit. "state of defence") are declared by a presidential decree, given after a motion by the government, which is then submitted to the Parliament for ratification.
