Boehner's office released a draft document on Thursday of the resolution set to be filed in the House of Representatives, which would authorize the chamber to take legal action against the president.
"Today we're releasing a draft resolution that will authorize the House to file suit over the way President Obama unilaterally changed the employer mandate," Boehner said in a statement.
"In 2013, the president changed the health care law without a vote of Congress, effectively creating his own law by literally waiving the employer mandate and the penalties for failing to comply with it. That's not the way our system of government was designed to work. No president should have the power to make laws on his or her own."
Boehner has hinted at the lawsuit for weeks, arguing Obama has continually overstepped his constitutional authority. Boehner sent a memo to the House Republican conference late last month, informing them of his plans to file legislation in July that would allow the House of Representatives to file suit to compel Obama to "faithfully execute the laws of our country."
He wrote in a CNN.com op-ed on Sunday that the House could target a number of specific executive actions as fodder for its lawsuit, including Obama's actions with regard to the Affordable Care Act, energy regulations, foreign policy, and education.
The White House and the president himself have jokingly dismissed the lawsuit. Most notably, Obama taunted House Republicans during a speech last week in which he pressed them to find a solution to replenish the Highway Trust Fund.
"I told him, I'd rather do things with you, pass some laws, make sure the Highway Trust Fund is funded so we don't lay off hundreds of thousands of workers. It's not that hard," Obama said of Boehner.
"Middle-class families can't wait for Republicans in Congress to do stuff. So sue me. As long as they're doing nothing, I'm not going to apologize for trying to do something."
