Traditional Three Standards of Review

Minimum Scrutiny Test:
Are the means rationally related to a legitimate government objective?
(The burden is on the challenger to show that there is either no legitimate government purpose for the law or that there is no rational relationship between the means and the end.)

Intermediate Scrutiny Test:
Are the means substantially related to an important government objective?
(The burden is on the government to show that there is an important government purpose to justify the law and that the means employed are substantially related (or narrowly tailored) to further that purpose.)

Strict Scrutiny Test:
Are the means necessary to the accomplishment of a compelling government objective?
(The burden is on the government to show that there is a compelling government purpose to justify the law and that the means employed are necessary (or narrowly tailored) to the accomplishment of that purpose. This requires a showing that there are no other less restrictive alternative means available to accomplish the compelling purpose.)
