NEW DELHI: The Centre has shot down the deputation request of forest service officer Sanjiv Chaturvedi , whom Delhi Chief Minister Arvind Kejriwal wanted to be posted as OSD in his office, saying service rules bar such hiring.It said that Chaturvedi needs to first complete mandatory cooling-off period of three years before joining the Delhi government.Chaturvedi, a 2002 batch Indian Forest Service officer of Uttarakhand cadre, is working as Deputy Secretary in All India Institute of Medical Sciences ( AIIMS ). He had last year sought inter-cadre deputation to Delhi government.Delhi Chief Minister Arvind Kejriwal had on February 16, last year written to Union Environment, Forest and Climate Change Minister Prakash Javadekar seeking services of Chaturvedi as Officer on Special Duty (OSD) in his office.The Appointments Committee of Cabinet ACC ) has declined the proposal for inter-cadre deputation of Chaturvedi from Uttarakhand cadre to the Government of National Capital territory of Delhi, an order issued recently by Department of Personnel and Training (DoPT) said.The decision comes after an order by Central Administrative Tribunal on June 2 directing the ACC to decide within three weeks on the deputation of the officer.After his induction into the service, Chaturvedi was allocated Haryana cadre. However, he sought change in the cadre citing "extreme personal hardship". The ACC had approved the inter-cadre transfer of Chaturvedi from Haryana to Uttarakhand in August 2015.However, in February this year, Uttarakhand government rejected a representation of Chaturvedi seeking a No-Objection Certificate for inter-cadre deputation stating "if government of India grants waiver of cooling off condition, Uttarakhand has no-objection for inter-cadre deputation".As per rules, an officer can get central deputation or inter-cadre deputation only after the concurrence from both the state government concerned (the cadre state of the officer) and the Centre.Further, an officer must serve three years cooling off period between the two central deputation tenure. The central deputation tenure of Chaturvedi comes to end on June 28.The Ministry of Environment, Forest and Climate Change (MoEFCC) had earlier informed the ACC that Chaturvedi was yet to serve in his new parent cadre i.e. Uttarakhand.The Ministry had further added that on account of the different socio-economic, political, cultural and geographical conditions from state to state, it was imperative for an officer to fully familiarise himself with the demand and constraints of his cadre in the formative stage of his career, in order to effectively meet the challenges of his cadre.In its recent communication dated June 16, the MoEFCC had said since the government of Uttarakhand has not accorded its consent, and the officer is required to complete the mandatory cooling-off in his cadre prior to consideration of his next deputation, the inter cadre deputation of Chaturvedi from Uttarakhand to Delhi government "cannot be considered".The ACC-led by Prime Minister Narendra Modi in its order issued on Tuesday declined the inter cadre deputation to Chaturvedi.
