stating that there was excess amount of Rs.38,804/- paid to the petitioner in the year 2009 and that was found in the 2010-2011 Audit, the second respondent, sent a direct communication to the petitioner, stating that an amount of Rs.16,000/- at the rate of Rs.8,000/- p.m was to be deducted for June and July 2011 and the balance has to be deducted in the month of August and September 2011 at the rate of Rs.8,000/- p.m and the balance of Rs.6,804/would be recovered in the month of October 2011. The impugned letter sent by the second respondent to the petitioner in Ou.Mu.1929/2011/A, dated 10.08.2011 is apparently erroneous, even in respect of the calculation made and that was also decided by the respondents, without providing any opportunity to the petitioner. However, the second respondent, after making a recovery at the rate of Rs.8,000/- p.m, in the month of June and July 2011, informed the petitioner, that the alleged balance would be recovered from the pension payable to the petitioner, which is against principles of natural justice, since the second respondent unilaterally decided some amount, without providing opportunity to the petitioner and stated that an excess payment was made and that would be deducted from the pension amount payable to the petitioner during June and July 2011.
