Musk was the biggest shareholder in both companies at the time of the deal and Tesla shareholders alleged he pushed the carmaker's board into the deal to bail out the billionaire's investment in the struggling rooftop solar company.
The state's highest court said that while a judge on the Delaware Court of Chancery erred in some portions of his analysis, his overall premise still supported his determination that Tesla paid a fair price for SolarCity.
They also argued that Slights determined after a 10-day trial in 2021 that Musk meddled in the deal but failed to hold him liable.
Shareholders wanted to force Musk to return the Tesla stock he received in the takeover, which at one point was worth $13 billion.
The Delaware Supreme Court said that the Slights' ruling was not "pitch perfect" but did not have to be and noted the "total collapse" of the shareholders' theory that SolarCity was insolvent.
