The Supreme Court said on Monday it will weigh in on the limits of whistleblower protections that are part of Obama-era Dodd-Frank financial reform law — potentially weakening protections for people who report wrongdoing in corporate America.

The high court will hear Digital Realty Trust Inc.’s case against Paul Somers, an executive fired by the company after he reported internal misconduct.

Digital Realty argues that Somers, who complained that executives had hidden cost overruns for a Hong Kong project, didn’t have protection from firing because he didn’t report the misconduct to the Securities and Exchange Commission.

“Good people standing up to do the right thing could be hurt,” Jordan Thomas, partner at Labaton Sucharow, where he heads whistleblower representation, told The Post. “An adverse decision would be a tragedy for all the key stakeholders.”

Whistleblower tips have risen rapidly since the Dodd-Frank financial reform law was passed in 2010, which strengthened protections and upped the amount that someone could collect from enforcement actions.

The SEC has awarded more than $154 million to whistleblowers since the first payment 2011.

The court will hear the case during its next term, which starts in October.
