had left his place of duty on 05.02.2006 and thereafter, he went to Asansole and somebody who knew the petitioner saw the mental condition of the petitioner and informed his relatives and thereafter, he was brought to Ranchi and on 07.08.2006, the petitioner was taken to Dr. Ashok Kumar Prasad, a Mental Decease Specialist of RIMS. However, from the writ record, the said Dr. Ashok Kumar Prasad has certified that the petitioner was under his treatment since 07.02.2006 to 02.04.2009. Thus, the stand of the petitioner in the writ petition that he was taken to Dr. Ashok Kumar Prasad on 07.02.2006 and the certificate shows that he was under the treatment of Ashok Kumar Prasad from 07.02.2006 cannot be reconciled. The stand of the petitioner about his mental illness from 07.02.2006 to 02.04.2009 being under treatment of Dr. Ashok Kumar Prasad is falsified by the specific plea of the writ petitioner himself. This Court also finds that as per the case of the petitioner, he left the place of duty on 05.02.2006 and while leaving, he had mentioned it in the register itself that he was not well and was going to Asansole to buy medicine. This conduct of the petitioner itself goes to show that the petitioner was capable of understanding and was conscious of the fact that he was leaving his place of duty and such conduct indicates mental alertness of the petitioner. Admittedly he did not seek any permission or informed his higher authority before leaving his place of duty and did not return. Considering the totality of the facts and circumstances of the case, the plea of mental illness taken by the petitioner appears to be an afterthought.
