Rosaiah had Saturday told reporters that he sent a letter to the governor requesting him to allow the ministers to continue without having to take oath afresh.
However, the governor sent a letter to the chief minister's office that the ministers would have to take oath again.
Advocate General D.V. Sitaram and Chief Secretary P. Ramakant Reddy also met Rosaiah and the governor to discuss the issue.
Rosaiah apprised the Congress party's central leadership of the situation as the high command has already made it clear that his taking over as chief minister was only a temporary arrangement.
Amid the growing demand to make YSR's son Y.S. Jaganmohan Reddy as the next chief minister, the central leadership said it would take a decision on the leadership issue only after the seven-day mourning period is over.
