Which class is categorized as a quasi-suspect class?

A quasi-suspect class is a category that is subjected to heightened scrutiny under the Equal Protection Clause of the Fourteenth Amendment, but not to the same extent as a suspect class such as race. Gender is classified as a quasi-suspect class because laws or policies that differentiate based on gender must serve an important government interest and must be substantially related to achieving that interest. This means that while gender discrimination is not automatically deemed impermissible, it is subject to a more rigorous standard of review than classifications that do not fall under this category.

In contrast, race is considered a suspect class, where any form of discrimination is often subject to strict scrutiny, requiring a compelling government interest to justify any differential treatment. Religion is not categorized as a quasi-suspect class but is also granted robust protections against discrimination, warranting strong scrutiny as well. Age falls into a different category and typically receives a rational basis review, which is the least stringent level of scrutiny. Therefore, gender's classification as a quasi-suspect class is significant in legal contexts, as it influences how courts evaluate gender discrimination cases.
