His statement at a news conference Thursday left no leeway at all.
He said the Hastert Rule would also apply to any legislation that results from a conference committee between the House and Senate -- the likely result of the House's plan to pass its own immigration bill, rather than the Senate's version.
"For any legislation, including a conference report, to pass the House, It’s going to have to be a bill that has the support of the majority of our members," Boehner said.
But even as two-thirds of the Senate is on-board, only about one-third of Senate Republicans are set to vote for it. If a similar portion of the House GOP conference supported an immigration bill, it wouldn't come to a vote under the Hastert Rule.
The speaker's decision effectively means that in order to pass, any immigration legislation would need the support of a majority of House Republicans, a majority of the House overall, and likely at least 60 senators.
