Dear Mr. Brijesh,
The following is an extract of a portion of the judgment of the Honourable Supreme Court of India in Gammon India Ltd. vs Niranjan Dass reported in 1984 (1) LLN 90.
"In the course of the hearing of this appeal, it was stated that the respondent has reached the age of superannuation; therefore, physical reinstatement in service is not possible. The appellant will have to establish that fact. But in the event the appellant shows that under a valid rule, the respondent has reached the stage of superannuation, and therefore physical reinstatement is not possible, it is hereby declared that the respondent shall continue to be in service uninterruptedly from the date of the attempted termination of service till the date of superannuation. The respondent would be entitled to all back wages, including the benefit of revised wages or salary if during the period there is a revision of pay-scales with yearly increments, revised dearness allowance or variable dearness allowance, and all terminal benefits if he has reached the age of superannuation, such as Provident Fund, Gratuity, etc. Back wages should be calculated as if the respondent continued in service uninterrupted. He is also entitled to leave encashment and bonus if other workmen in the same category were paid the same."
The above extract directly answers your query. You can read the full judgment on the official website of the Honourable Supreme Court of India.
