Which principle is associated with the use of 'strict scrutiny' in constitutional law?

The principle associated with the use of 'strict scrutiny' in constitutional law is the principle of equality. Strict scrutiny is the highest standard of judicial review that courts apply when assessing whether a law or policy is constitutional, particularly when it involves classifications based on race, ethnicity, or national origin. Under this framework, the government must demonstrate that the law serves a compelling state interest and is narrowly tailored to achieve that interest.

This principle ensures that laws promoting equality are closely examined to prevent discrimination and protect the rights of individuals who may be vulnerable to unfair treatment. In essence, strict scrutiny acts as a safeguard against laws that may infringe upon fundamental rights or create discriminatory practices, reinforcing the commitment to equality under the law.

The other principles mentioned, while important in constitutional law, do not specifically relate to the rigorous analysis applied through strict scrutiny in the context of equality concerns.
