One of the country’s strictest — and controversial — bans on hydraulic fracturing may be in jeopardy.

Earlier this month, voters in Mora County ousted the man who spearheaded an ordinance giving the local government the power to permanently keep the entire county’s 1,933 square miles off-limits to any development of hydrocarbons — something critics say eradicates private property rights. The ban also prohibits hydraulic fracturing, also known as “fracking.”

The defeat of commissioner John Olivas by more than 25 points to George Trujillo, could mean trouble for the ban, which has plunged the county into two potentially expensive lawsuits.
