These columns fought the Affordable Care Act from start to passage, and we'd now like to apologize to our readers. It turns out we weren't nearly critical enough. The law's implementation is turning into a fiasco for the ages, and this week's version is the lawless White House decision to delay the law's insurance mandate for businesses, though not for individuals.

The employer mandate is central to ObamaCare's claim of providing universal coverage. Companies with 50 or more "employee equivalents" must pay a $2,000 penalty per full-time employee if they don't provide government-approved health insurance. The provision was supposed to start in January, and delaying it is like Ford saying its electric car is ready to go, except the electric battery doesn't work.

But all of a sudden on Tuesday evening Mark Mazur—you know him as the deputy assistant Treasury secretary for tax policy—published a blog post canceling the insurance reporting rules and tax enforcement until 2015 as Washington began to evacuate for the long Independence Day weekend. Enjoy the holiday, mate.

White House fixer Valerie Jarrett tried to contain the fallout with a separate blog post promising that ObamaCare is otherwise "staying the course." That's true only if she's referring to the carelessness and improvisation that have defined the law so far.

Mr. Mazur cited the "complexity of the requirements" as the reason for the delay. He isn't talking about business confusion and uncertainty, as damaging as those are. This is probably an admission that Treasury's information technology isn't ready to process and cross-check paperwork across the 5.7 million businesses in America, especially the pass-through S-corps and partnerships that file under the individual tax code.
