In two rulings Tuesday, the justices took an expansive view of civil rights law.
American workers who complain about race or age discrimination on the job can sue their bosses for any subsequent retaliation.
In two decisions announced on Tuesday, the US Supreme Court embraced an expansive view of certain civil rights laws that do not explicitly outlaw acts of retaliation.
Nonetheless, the majority justices said the overall purpose of the laws suggests an intent by Congress to prevent discrimination – including retaliation aimed at punishing those who file age- or race-discrimination complaints.
At issue in both cases was whether Congress had created a cause of action in the law to permit retaliation lawsuits.
While some laws, such as Title VII of the Civil Rights Act of 1964, ban retaliation in response to any discrimination complaint, other important civil rights laws make no mention of retaliation.
The majority justices ruled that employees can claim legal protections against retaliation even if the law does not specifically bar acts of retaliation.
Writing for the majority in one of the cases, Justice Stephen Breyer cited two prior decisions of the high court in 1969 and 2005 as supporting an expansive view of such laws. "We believe it is too late in the day in effect to overturn the holding in that  case," Justice Breyer writes for the seven-justice majority in CBOCS West, Inc. v. Humphries.
In a dissent, Justices Clarence Thomas and Antonin Scalia said if Congress intended for a law to cover retaliation it would have said so in the statute. "The court does not even purport to identify any basis in the statutory text for the 'well-embedded interpretation [of the law]' it adopts for the first time today," Justice Thomas writes. Unlike the court, he said he found the statute's text conclusive.
