■ Freedom from Veto
The strength of a legislature is also influenced by its degree of autonomy in its core discipline, the law making process. In most countries, the Head of State must sign or otherwise promulgate the law before it enters into force. However, the relevant question is not the mere involvement of the executive, but the substantive impact this involvement might have on the legislature’s powers. Various degrees of interference by a Head of State might hamper the legislative process. As long as the executive does not set a higher additional threshold for passage of the law, the legislature’s power remains intact.
