It was held by this Court 510 that granting to Mr. Beuria the salary of the Registrar with effect from December 1, 1948 was erroneous, as it was grant ed to him on the misconstruction of the relevant rule and, thereafter, it was observed as follows: "If the respondent 's plea of discrimination was accepted on the strength of the single case of Mr. Beuria, it would follow that because the appellant placed a misconstruction on the relevant Rule, it is bound to give effect to the said misconstruction for all times; that, plainly cannot be said to be sound."
