Royal Assent - United Kingdom

United Kingdom

In the United Kingdom the Royal Assent is the final step required for a parliamentary bill to become law. Once a bill is presented to the Sovereign or the Sovereign's representative, he or she has three formal options. Firstly, the Sovereign may grant the Royal Assent, thereby making the bill an Act of Parliament. Secondly, the Sovereign may withhold the Royal Assent, thereby vetoing the bill. Finally, the Sovereign may reserve the Royal Assent, that is to say, defer a decision on the bill until a later time.

Under modern constitutional conventions, the Sovereign acts on the advice of his or her ministers. Since these ministers most often maintain the support of Parliament and are the ones who obtain the passage of bills, it is highly improbable that they would advise the Sovereign to withhold Assent. An exception is sometimes stated to be if bills are not passed in "good faith", though it has been difficult to make an interpretation on what this might constitute. Hence, in modern practice, the Royal Assent is always granted; a refusal to do so would only be appropriate in an emergency situation requiring the use of the monarch's reserve powers.
