President Barack Obama’s latest legal end run around Congress — delaying enforcement of the employer health mandate — has sparked more questions about whether he’s abusing his executive discretion under the Constitution.

The move announced late Tuesday was the latest in a string of decisions where the president, facing a divided Congress unable to get much done beyond keeping the government running, has taken matters into his own hands.

Where a previous president might have asked for a legislative fix if a mandate was proving too onerous for business, the Obama administration put out a couple of blog posts saying that, in listening to the business community, it decided not to enforce a key part of the 3-year-old health law for another year.

The administration notes that parts of laws are delayed in implementation all the time — including various pieces of the tax code.

A Treasury official said the administration has “longstanding administrative authority to grant transition relief when implementing new legislation like the ACA.”
