Case Note & Summary
The appeal arose from a judgment of the Division Bench of the High Court of Calcutta dated 25 January 2019, which upheld a circular dated 3 July 2012 issued by the Kolkata Municipal Corporation. The circular prescribed separate conditions for diploma and degree holder Sub-Assistant Engineers for supernumerary appointments as Assistant Engineers, along with a gradation list dated 5 July 2012 prepared pursuant to the circular. The appellants, who were Sub-Assistant Engineers possessing diplomas in engineering, had instituted a writ petition before the High Court challenging the circular and gradation list on grounds that classification within the same cadre for supernumerary appointments violated Articles 14 and 16 of the Constitution. A Single Judge of the High Court allowed the writ petition on 6 October 2015, holding the circular arbitrary and unconstitutional. However, in a Letters Patent Appeal, the Division Bench reversed this decision and upheld the validity of the classification based on educational qualifications. The Kolkata Municipal Corporation had two distinct service cadres in its Engineering Department: Subordinate Engineering Service and Engineering Service. The entry post in Subordinate Engineering Service was Sub-Assistant Engineer, for which the minimum qualification was a diploma in engineering, though degree holders were also eligible. The Recruitment Regulations provided for promotion from Sub-Assistant Engineer to Assistant Engineer, with various modifications over time regarding quotas for promotion based on experience and qualifications. To address stagnation in promotions, the Corporation issued the impugned circular creating supernumerary Assistant Engineer posts for Sub-Assistant Engineers, with different service requirements: twenty-five years for diploma holders and thirteen years (with five years as degree holders) for degree holders. The core legal issue was whether this classification based on educational qualifications violated constitutional guarantees of equality. The appellants argued that when persons with different educational qualifications undergo a common recruitment process, subsequent classification within the cadre is impermissible. The respondents contended that the classification was reasonable and aimed at administrative efficiency by addressing stagnation. The Court analyzed the legal position, noting that classification based on educational qualifications is permissible under Articles 14 and 16 if it has a rational nexus with the object sought to be achieved. The Court found that the impugned circular did not alter existing promotional avenues but created supernumerary posts to address stagnation, with these posts to be adjusted against permanent vacancies. The classification was reasonable as it recognized the higher qualification of degree holders while providing relief to diploma holders after longer service. The Court upheld the Division Bench's judgment, finding no constitutional violation. The appeal was dismissed, and the circular and gradation list were sustained.
