Purpose: This study aimed to identify and analyze the experience of passing and repealing the Nurses Act in Parliament. Methods: This qualitative study used content analysis. The data were collected through in-depth interviews October 16 to November 23, 2023. Results: The qualitative content analysis revealed five themes and 16 subthemes. The themes included: “Learning the Nurses Act through different channels”, “The Nurses Act’s passage, which strengthens the professionalism and legitimacy of the nursing profession”, “Looking back and feeling the joy and frustration of the process of getting it through the Congress and getting it repealed”, “An abandoned nursing practice due to bullying”, “Nevertheless, moving toward the re-enactment of the Nurses Act with hope”. Conclusion: Nurses expected the Nurses Act to recognize their expertise and clarify legal nursing practices; however, they were outraged and perplexed when the president vetoed the Nurses Act, and they felt sorry for the Nurses Act, which was turned into a political tool in the conflict between medical professions. Nevertheless, they hoped that the Nurses Act would be re-promoted through opinions and discussions with various professions and public awareness activities by developing nurses’ political capabilities and preparing a basis for the Nurses Act.
