I was denied a Kolkata government benefit that others got; does Article 14 help?

Article 14 guarantees equality before the law and equal protection of the laws, which includes the right against arbitrary state action. Denying a benefit to one person while granting it to similarly placed others without a reasonable classification is violative of Article 14. File a writ petition under Article 226 in the Calcutta High Court challenging the denial and seeking a mandamus to grant the benefit. The court will examine whether the classification has a rational nexus to the objective and whether the denial was arbitrary. West Bengal Premises Tenancy Act 1997 that grants the benefit must be applied uniformly, and any executive deviation can be struck down as arbitrary. Collect the order denying the benefit, the orders granting it to others, and the relevant scheme document in Kolkata. The court can direct the authorities to extend the benefit to you and to pay the arrears with interest.
