The Washington Order of Justification (WON) is a legal doctrine developed by the Washington Supreme Court to determine the constitutionality of a law. The WON requires judges to consider the purpose of the law, the necessity of the law in order to achieve its purpose, and the proportionality of the law to its purpose. There are three types of Washington Order of Justification: strict scrutiny, intermediate scrutiny, and rational basis. Strict scrutiny is the highest level of judicial review, and is used to evaluate laws that interfere with certain fundamental rights. Intermediate scrutiny is used to evaluate laws that interfere with important rights, and rational basis is used to evaluate all other laws. The court will evaluate the law according to the level of scrutiny appropriate to its purpose, and if it fails to meet the standard, the law will be struck down.
