We are of the opinion that the second notification, without (taking away the obligation imposed by the first notification on Government employees owning houses in their own names or in the name of any other member of their families, within the limits of their place of posting, to vacate the Government accommodation within three months from the first of October 1975, has given an option to those employees to continue to occupy the Government accommodation subject to the obligation mentioned in the second notification, namely, that the house owning Government employee will have to pay normal rent for the Government accommodation if the income from his own house does not exceed Rs. 1,000 per mensem of half the market rent if the income from his own house exceeds Rs. 1,000 per mensem but does not exceed Rs. 2,000 per mensem and full market rent if the income from his house is above Rs. 2,000 per mensem with effect from 1.6.1977.
