“ 29. Rival submissions of the parties have been duly considered. The decision to grant pension to casual Muster Roll Workers whose services were regularized and have completed 20 years of total service cannot, per se, be termed as arbitrary. The question which rises for determination is whether the decision contained in the Office Memorandum dated 20.05.2009, to deduct 6 years of service meet the test of reasonability under Article 14 of the Constitution of India. While determining the aforesaid question, the Court is reminded of the fact that the petitioners belong to the economically lower strata of the society. As has been held by various judicial pronouncements, it has been laid down that pension is not a bounty or a grace but valuable right accruing by an employee if he fulfills the conditions to be entitled for such pension. The conditions imposed in the instant case for the petitioners who are Muster Roll Workers is completion of a total period of continuous service of 20 years. While this Court, as has been observed above, does not hold that fixation of 20 years of continuous service an arbitrary, the deduction of 6 years does not appear to be reasonable and fair. this Court does not find force that the exercise, in publishing the notification dated 20.05.2009 itself was an under Rule 31 of the Rules and therefore, further exercise is not permissible. It will be wholly unfair and unreasonable to deny a Muster Roll Worker who is admittedly completed 20 years of continuous service of pension in terms of Office Memorandum dated 06.09.2003. However, deduction of 6 years or for that matter, any period to calculate 20 years of continuous service, does not appear to be reasonable. The entire exercise of issuing the notification should be in a positive manner so as to ensure that maximum benefit is given to the incumbents who undoubtedly belong to the economically lower strata of the society. It should have been the endeavour of the State not to make a further classification of Muster Roll Workers who have completed 20 years of continuous service by introducing the condition of deduction of 6 years of casual service. Admittedly, there is no difference at all between the services rendered by the petitioners while they were employed in a casual manner or after the regularization.
