The application of the
Oncale case has caused some difficulty in the lower federal courts, which have struggled with how to determine whether any particular case of same-sex harassment is "because of sex." In particular, courts have struggled with how to deal with harassment that appears to be based on actual or perceived
sexual orientation because
employment discrimination based on sexual orientation was not explicitly forbidden by federal law. In July 2015, the
Equal Employment Opportunity Commission determined that employment discrimination based on sexual orientation was illegal under Title VII of the Civil Rights Act of 1964 and used the
Oncale decision as a basis
. Because it set a precedent regarding harassment "because of sex,"
Oncale v. Sundowner has been lauded as a landmark
gay rights case, even though all those involved were heterosexual. In the Court's opinion in
Oncale, the inclusion of sexual discrimination between same sex individuals as a protected class under Title VII set an important precedent of expanding the interpretation of protected classes under § 2000e-2(a)(1). This precedent was later reflected upon in
Bostock v. Clayton County along with two other important cases, all of which considered the word "sex" and its definition in regards to Title VII of the Civil Rights Act of 1964. ==See also==
