New Delhi: A top adviser has been replaced by Army Chief General V K Singh.

Brigadier A K Singh will take over from Brigadier S T Upasani as the Military Adviser to the Army Chief, who gives suggestion to him on key matters related to the Service, sources said here on Monday.

They said Brig Singh from the Punjab Regiment, will take charge from Brig Upasani, who is now scheduled to proceed on a higher command course, in a few weeks.

Gen Singh filed a petition in the Supreme Court on Monday challenging the government's rejection of his claim on his date of birth.

He says his date of birth is May 10, 1951 as per his matriculation certificate but the Defence Ministry recently rejected his contention, arguing that his date of birth entered in some Army records was May 10,1950.

As per the government decision, he will retire on May 31 this year but if his contention is upheld, he will get tenure till March 2013.

In his own petition, the Army Chief has contended that he was treated by the government in a manner which reflects total lack of procedure and principles of natural justice in deciding his age.
