On June 28, the Kuomintang legislative caucus locked the door of the Legislative Yuan and sprayed paint over its opposition to the Control Yuan nominee list. The Democratic Progressive Party caucus and councilors slashed the chains locking the door with hydraulic shears at 11 a.m. and entered. KMT Chair Johnny Chiang told the DPP if anyone is injured, the DPP will have to take full responsibility. He also said what the DPP really removed was public sentiment that it had damaged Taiwan's democracy.
The Kuomintang caucus began occupying the legislature on the night of the 28th, blocking the front door with chairs and locking it with chains. KMT Chair Johnny Chiang, caucus convener Lin Wei-chou, and lawmaker Chiang Wan-an chained themselves together inside. A spray-painted message calls for the Control Yuan nominee list to be withdrawn, with particular opposition for Chen Chu's nomination as Control Yuan president. The legislative speaker ordered the chains to be severed with hydraulic shears. The chairs are not what's blocking the door today. What's blocking the door are your unsuitable nominations and your political rewards. What we are blocking are your political rewards and your unsuitable nominations. Cross-party consultations that were supposed to be held on the 29th did not happen with the KMT caucus occupying the floor of the legislature. DPP lawmakers therefore went up to press row on the second floor to yell at them. They're completely irrational and unreasonable in their attacks calling for Chen Chu to be replaced. This is unacceptable. We call on the four parties to be rational and for procedure to be restored. Outside the legislature, retired military personnel and their supporters gathered to show support for the KMT. Hundreds of police were sent to the scene to set up roadblocks around the legislature and keep the group in line. 國民黨立委高喊口號，從前一天晚上就夜守議場，不只用椅子、鐵鍊，把出入口都擋住，國民黨主席江啟臣、黨團總召林為洲，還有蔣萬安也綁在一起，桌上更噴上綠色大字，要求撤回監察院人事提名名單，尤其是院長陳菊的提名，他們態度堅決，不撤回陳菊，就會反對到底。 國民黨主席 江啟臣表示：「聽說立法院院長下令，要用油壓剪，剪掉鐵鍊。必須告訴大家，今天這些椅子，擋住的不是門，擋住的，是你不適任的提名；擋住的，是你的酬庸。我們要擋的，是酬庸；我們要擋的，是不適任的提名。」 原訂29號上午的黨團協商，也因為國民黨拒絕出席，協商破裂，10點半的談話會，也因為議場被國民黨攻佔，無法進行，多位民進黨立委乾脆到二樓記者席，和藍營空中對話。 立法院民進黨團總召 柯建銘表示：「用不理性的、毫無道理的說，陳菊必須換掉，這不可能接受。」 立法院長 游錫堃表示：「呼籲四個黨，就是說，各黨，大家都能回歸理性， 然後回歸程序。」 場內抗議，場外則有八百壯士號召支持者，用行動聲援。 面對抗議群眾，警方出動上百名警力，嚴陣以待，立法院四周都是層層拒馬，就擔心發生衝突。
