disability should be 40%. As far as persons with disability in vision are concerned, only blind employees are entitled to conveyance allowance as per Ext.P2. But for employees having disability in vision, by Ext.P4 Government order, a relaxation was given and instead of blind employees, Government servants having vision less than 3/60 or field vision less than 10 degree in both eyes also were made eligible for grant of conveyance allowance in terms of Ext.P2 Government order. Therefore, according to the learned Standing Counsel for the 3rd respondent, the petitioner is not entitled to conveyance allowance, because, as is revealed from Ext.P1 disability certificate, orthopedic disability and disability in vision of the petitioner together come only to 40%. Therefore, the petitioner's orthopedic disability is less than 40% and she has one good eye insofar as she is blind only in one eye. The learned Government Pleader submits that, therefore, the petitioner is not entitled to conveyance allowance as per Exts.P2 and Government orders and the amounts already paid had been made under a mistake.
