BOSTON (CBSDFW.COM/AP) — Massachusetts’ highest court has ruled that Exxon Mobil must hand over documents related to a state investigation into whether the company misled the public about the impact of fossil fuels on climate change.

The Supreme Judicial Court sided Friday with Attorney General Maura Healey, who’s trying to determine whether Exxon Mobil concealed information it knew about climate change from consumers and investors.

The court rejected Exxon Mobil’s argument that the attorney general should be disqualified from the investigation because of comments Exxon says show bias against the company.

The high court’s decision upholds a lower court ruling against the Irving, Texas-based oil and gas giant.

Exxon officials didn’t immediately respond to a request for comment.

New York Attorney General Eric Schneiderman is conducting a similar probe.
