Dear Mr.Vinayak,
Perhaps the point you raised is a valid question of law and as such can be subject to judicial review if the employer chooses explicitly not to pay the subsistence allowance at the enhanced rate so long as the lock down continues as a situation beyond his reasonable expectation or control;that's fine.
However, before such a decision, it is imperative to analyze the concepts of suspension and subsistence allowance in the realm of employment as part of disciplinary proceedings either anticipated or in progress. It is not necessary that every disciplinary proceeding, anticipated or in progress against an employee, would warrant suspension. It is the serious nature of the misconduct alleged and the possibility of the delinquent's meddling with the documents or influencing the witnesses, if any to his favour are the factors to keep him temporarily out of his official position. Therefore, the employer is the sole judge to decide the matter and thus it is a matter of discretion only. If placed under suspension pending enquiry, the delinquent is deprived of his earnings out of the contract of employment which is kept under animated suspension only though he is bound to submit himself to the proceedings as and when required. That's the objective behind the sanction of subsistence allowance during the entire period of suspension. At the same time the enhancement of its rate of payment linking to the suspension period's different spells emanates from the need for the expeditious disposal of the disciplinary proceedings by the employer to ward off any unfair labor practice under the pretext of suspension. Therefore, it is not necessary that every disciplinary proceeding and the delinquent's suspension should be concurrent and concomitant.
If we analyze the situation presented by Mr.Mayank-lad in this back drop, what would require our attention to refute enhanced rate of subsistence allowance beyond the first or subsequent spell of suspension is whether the delay is attributable on the part of the suspended employee only. If the answer is "no", then he is entitled to enhanced rate of subsistence allowance as long as he is under suspension pending enquiry. The difficulty if any like the intervening lock down faced by the employer cannot be a reasonable ground against enhancement of the rate of subsistence allowance thus prescribed in the service regulations or the contract of employment for it is only a concession to the prolonged suspension.
