The Delhi government has suspended two of its senior-most DANICS officials posted as special secretaries with the Home department late Tuesday, as they had allegedly refused to sign two cabinet notes. The move could lead to yet another tussle between the government and the Lieutenant Governor, as only the Lt Governor can suspend senior DANICS officials with permission from the Home Ministry. In that case, sources said, the suspension could be deemed invalid. The officials have been identified as Subhash Chandra, special secretary, prisons, and Yashpal Garg, special secretary, prosecution. They belonged to the senior administrative grade, the highest grade in DANICS.
