Intermediate Scrutiny in Constitutional Law: Understanding Its Role, Applications, and Impact on Equality and Government Policy

In constitutional law, courts often face the challenge of determining whether a law that restricts individual rights is justified. Governments sometimes pass laws that treat different groups of people differently, and courts must decide whether such treatment violates constitutional protections.

To evaluate these laws, courts use different levels of judicial review. One of the most important among them is scrutiny. It is a legal standard used primarily by courts in the United States to evaluate whether a government action or law that classifies individuals or restricts certain rights is constitutional.

It sits between two other important standards: rational basis review and strict scrutiny. While rational basis review is the most lenient and strict scrutiny is the most demanding, intermediate scrutiny represents a balanced approach.

Aspect	Key Points
Definition	Middle-level judicial review for laws treating groups differently.
Requirements	Important governmental interest; substantially related to achieving it.
Applications	Gender discrimination, legitimacy classifications, and content-neutral speech regulations.
Examples	Employment, military, family law, education, time/place/manner speech rules.
Major Cases	Craig v. Boren, United States v. Virginia, Mississippi Univ. for Women v. Hogan.
Difference from Strict Scrutiny	Less strict: important interest vs. compelling; substantially related vs. narrowly tailored.
Level of Difficulty	Moderate, between rational basis and strict scrutiny.
Criticisms	Judicial discretion, inconsistent rulings, unclear boundaries, and debate on gender cases.
Purpose	Prevents unfair discrimination while allowing legitimate government action.
Importance	Protects equality, balances rights and government power, and encourages fair policymaking.

What Is Intermediate Scrutiny?

It is a legal standard used by courts to evaluate the constitutionality of laws or government actions that treat different groups of people differently. It serves as a middle level of judicial review, positioned between the highly deferential rational basis review and the very strict strict scrutiny standard.

Under intermediate scrutiny, a law or policy will only be considered constitutional if it meets two key requirements: first, the government must demonstrate that the law serves an important governmental interest, and second, the law must be substantially related to achieving that interest.

This means the law cannot rely on arbitrary distinctions, stereotypes, or convenience; there must be a meaningful connection between the classification created by the law and the governmental objective it aims to achieve. It is most applied in cases involving gender discrimination and classifications based on legitimacy.

The Three Levels of Judicial Scrutiny

To fully understand scrutiny, it is necessary to understand the three levels of judicial scrutiny used in constitutional law.

1. Rational Basis Review

This is the lowest level of judicial scrutiny.

Under rational basis review:

• The government only needs to show that the law has a legitimate governmental purpose.
• The law must be rationally related to achieving that purpose.
• Courts usually defer to the government under this standard, meaning most laws survive rational basis review.
• This level is commonly used in cases involving economic regulation or social welfare policies.

2. Intermediate Scrutiny

• The government must show an important governmental interest.
• The law must be substantially related to achieving that interest.
• Courts apply this standard when laws involve certain types of discrimination, particularly those based on gender or legitimacy.

3. Strict Scrutiny

Strict scrutiny is the highest and most demanding level of judicial review.

For a law to survive strict scrutiny:

• The government must show a compelling governmental interest.
• The law must be narrowly tailored to achieve that interest.
• It must be the least restrictive means available.

Strict scrutiny is typically applied in cases involving:

• Race-based discrimination
• Fundamental rights such as voting or freedom of speech.

Historical Development

This did not exist in early constitutional law. Instead, courts primarily relied on rational basis review. During the mid-20th century, courts began recognizing that certain forms of discrimination deserved more careful examination than rational basis review but did not necessarily require strict scrutiny.

The concept of scrutiny developed gradually through judicial decisions, particularly in cases involving gender discrimination. The turning point came in the 1970s when courts began formally applying this standard in gender equality cases.

Key Legal Requirements of Intermediate Scrutiny

The government must demonstrate that the law serves an important objective. This objective must be significant enough to justify differential treatment.

Examples of important interests include:

• Public safety
• Administrative efficiency
• Protection of vulnerable populations
• However, mere convenience or traditional beliefs are usually not enough.

Substantial Relationship

The law must also be substantially related to achieving the government’s objective.

This means:

• The classification created by the law must directly contribute to achieving the intended goal.
• The connection between the law and the objective must be meaningful.
• If the relationship between the law and the objective is weak or speculative, the law will fail scrutiny.

Areas Where Intermediate Scrutiny Is Applied

Context	Description	Examples	Purpose
Gender-Based Classifications	Laws or policies that treat men and women differently	– Employment opportunities- Military service- Family law- Education policies	Courts evaluate whether the gender-based distinction genuinely serves an important governmental objective and ensure fairness in treatment

Legitimacy Classifications

It is also applied in cases where laws discriminate against children born outside of marriage, historically referred to as “illegitimate children.” Courts use this standard to carefully examine whether such laws are justified by an important governmental objective.

The purpose of applying intermediate scrutiny in these cases is to ensure that individuals are not unfairly treated or disadvantaged because of circumstances beyond their control, such as the marital status of their parents. By reviewing these laws more closely, courts aim to protect the rights of these individuals and promote fairness and equality within the legal system.

Certain First Amendment Cases

• In some First Amendment cases, courts apply scrutiny when evaluating certain regulations on speech.
• This standard is mainly used for content-neutral regulations, which control speech without targeting specific ideas or viewpoints.
• The purpose of these regulations is usually to manage how speech occurs rather than restrict what is being said.
• Courts examine whether the regulation serves an important governmental interest and is appropriately related to that objective.

Examples Include

• Time restrictions on when speech or protests may take place
• Place restrictions on where demonstrations or public gatherings can occur
• Manner restrictions on how speech is expressed, such as limits on noise levels
• Certain regulations affect symbolic expression, such as rules about public demonstrations or displays.

Major Court Cases Establishing Scrutiny

Craig v. Boren (1976)

This case formally established scrutiny for gender discrimination. The case involved a law in Oklahoma that allowed women to purchase low-alcohol beer at age 18 but required men to wait until age 21.

The Supreme Court ruled that the law violated the Equal Protection Clause because the gender-based distinction was not substantially related to the state’s objectives. This case clearly defined the scrutiny standard.

United States v. Virginia (1996)

This case involved the Virginia Military Institute (VMI), which historically admitted only male students. The Supreme Court ruled that the exclusion of women was unconstitutional.

The Court stated that gender-based classifications require an “exceedingly persuasive justification.” This strengthened the application of scrutiny.

Mississippi University for Women v. Hogan (1982)

In this case, a male applicant challenged a state-supported nursing school that admitted only women. He argued that the policy was discriminatory and violated the Equal Protection Clause of the Constitution. After reviewing the case, the Supreme Court determined that the exclusion of men from the nursing program was unconstitutional.

The Court concluded that the gender-based policy did not serve an important governmental objective and therefore failed to meet the requirements of intermediate scrutiny. This ruling strengthened the principle that laws or policies based on gender must be carefully examined by courts to ensure that they are justified.

Intermediate Scrutiny in the First Amendment

It also appears in cases involving content-neutral regulations of speech.

For example, governments may regulate:

• Noise levels during protests
• Locations where demonstrations occur
• The use of public spaces for expression

In such cases, courts evaluate whether:

1. The government has an important interest.
2. The regulation directly advances that interest.
3. The restriction leaves open alternative channels for communication.

Criticisms of Intermediate Scrutiny

Although scrutiny plays an important role in constitutional law, it has also faced certain criticisms from legal scholars and experts. One of the main concerns is the lack of clear boundaries in its application. Some scholars argue that the distinction between rational basis review and scrutiny is not always precise or clearly defined.

Because scrutiny allows a degree of judicial discretion, critics believe that the standard can sometimes produce inconsistent decisions depending on how strictly or loosely judges interpret the requirements of the test.

Judicial Subjectivity

• Critics argue that scrutiny gives judges significant discretion in interpreting the law.
• Judges have the authority to decide what qualifies as an important governmental interest.
• Because of this flexibility, different judges may interpret the standard differently.
• As a result, court decisions may become inconsistent in similar cases.
• Outcomes may also vary depending on a judge’s judicial philosophy or legal perspective.

Debates About Gender Equality

Some legal scholars believe that cases involving gender discrimination should be evaluated under strict scrutiny rather than scrutiny. They argue that discrimination based on gender can be just as harmful and unjust as discrimination based on race.

Because of the serious social and legal consequences that gender discrimination can create, these scholars believe it deserves the highest level of constitutional protection. According to this view, applying strict scrutiny would ensure that governments must provide extremely strong and compelling reasons before creating laws.

Importance of Intermediate Scrutiny

Protecting Equality

It ensures that governments cannot casually discriminate against individuals based on gender or other protected classifications. This means that when a law treats people differently based on gender, the government must provide a strong and convincing reason for doing so.

Balancing Government Power and Individual Rights

This standard allows courts to strike a balance between protecting individual rights and allowing governments to pursue legitimate policy goals. Through scrutiny, courts ensure that individuals are not unfairly treated or discriminated against by government laws or policies.

Promoting Fair Legal Standards

By requiring that a law serve an important government interest and maintain a substantial relationship with that objective, scrutiny encourages lawmakers to carefully design policies that are fair, reasonable, and properly justified.

Intermediate Scrutiny in Modern Legal Debates

It continues to influence modern constitutional debates.

Courts still apply this standard in cases involving:

• Gender discrimination
• Educational policies
• Employment law
• Certain speech regulations
• Legal scholars and judges frequently discuss whether this standard should be expanded or modified as society evolves.

Conclusion

It is one of the most important standards of judicial review in constitutional law. Positioned between rational basis review and strict scrutiny, it ensures that laws involving certain classifications are examined carefully without completely preventing government action.

By requiring that laws serve an important governmental objective and be substantially related to achieving that objective, intermediate scrutiny protects individuals from unfair discrimination while allowing governments to pursue legitimate goals.
