Scandal-tainted nursing-care service Comsn Inc. signed an agreement Thursday with affiliate NSS Corp. to hand over its business and all of its employees, but the health ministry quickly objected and urged the firms to suspend the deal until the end of the business year in March.

The warning came a day after the ministry decided to shut down 80 percent of Comsn's operations over the next five years by refusing to renew licenses for 1,655 of its nursing homes due to evidence of fraud.

Both companies are subsidiaries of Goodwill Group Inc., a major staffing agency.
