A governor's efforts to combat Covid-19 in the US state of Kentucky suffered a legal defeat on Saturday as the state's high court cleared the way for new laws to rein in his emergency powers.
In a landmark separation-of-powers case, the Kentucky Supreme Court said the legislature wields policy-making authority to limit the emergency powers granted to the governor by state law, Associated Press reports. The ruling ordered a lower court to dissolve an injunction that for months had blocked the Republican-backed laws from curbing Democratic governor Andy Beshear's executive authority. The order could alter the state's response to the pandemic at a time when virus cases and hospitalisations have surged because of the Delta variant. The Supreme Court order will dissolve Kentucky's pandemic-related state of emergency, Beshear spokesperson Crystal Staley said
The next step is to determine whether lawmakers are willing to extend the state of emergency in a potential special session, she said.
