The Court of Appeals for the District of Columbia Circuit officially delayed its case on the Mercury and Air Toxics Standards rule.
The Trump administration requested the delay earlier this month, The Hill reported.
The case, brought forward by various business groups and 15 states, centers on a rule the Obama administration wrote last year to fix a problem with the cost-benefit analysis. Scott Pruitt, now the head of the EPA, litigated against the rule when he was Oklahoma’s attorney general.
The Trump administration said in its delay request that it is reviewing the 2016 rule to decide if it supports it. At this point, it’s unclear what this means for the MATS rule as a whole.
