Legal action: MARA Granbury Facility

Supreme Court of Texas issued an order denying the petition by MARA Holdings for a writ of mandamus in the proceeding linked to the Granbury nuisance case. The court also dismissed the motion to stay as moot. This procedural order does not decide the truth of the noise allegations or establish that the underlying concern was resolved.

Company statement published by an agency or court
