The promotion of cadres to the party group meeting, in turn, can cancel the previous resolution after changing the new director. The reasons are as follows: the decision-making power of the new director, the new work direction and focus, and the organization need to be changed.

1. Decision-making power of the new director: The new director has the decision-making power of cadre promotion and personnel arrangement. Once the new director takes office, he has the right to review and adjust the previous resolutions to ensure the suitability of cadres and meet the needs of the organization.

2. New work direction and focus: The new director has his own work direction and focus. They think that the previous decision on cadre promotion does not meet the new goals and requirements. So they will propose to cancel the resolution in order to rearrange the cadres.

3. Changes in organizational needs: With the passage of time, organizational needs and environment have changed. According to the current organizational needs, the new director re-evaluated the previous resolution and decided to cancel or adjust the previous resolution to adapt to the new situation. It should be noted that the cancellation of previous resolutions should be carried out under the discussion and decision of the party group meeting or relevant decision-making bodies. This decision involves many factors and trade-offs, aiming at ensuring that the selection and arrangement of cadres meet the needs and development direction of the organization.
