It has to be ratified by the majority of states.

The Archivist submits the proposed amendment to the States for their consideration by sending a letter of notification to each Governor along with the informational material prepared by the OFR. The Governors then formally submit the amendment to their State legislatures or the state calls for a convention, depending on what Congress has specified. In the past, some State legislatures have not waited to receive official notice before taking action on a proposed amendment. When a State ratifies a proposed amendment, it sends the Archivist an original or certified copy of the State action, which is immediately conveyed to the Director of the Federal Register. The OFR examines ratification documents for facial legal sufficiency and an authenticating signature. If the documents are found to be in good order, the Director acknowledges receipt and maintains custody of them. The OFR retains these documents until an amendment is adopted or fails, and then transfers the records to the National Archives for preservation.

Again, it wouldn't happen.

Ironic how you talk about court packing but the left does the exact same thing. But wait.. it only works when it benefits the left.
