Issues Involved:
1. Transfer and retransfer of the Slum Wing Department (SWD) between Municipal Corporation of Delhi (MCD) and Delhi Development Authority (DDA).
2. Recruitment and promotion rules for Junior Engineers, Assistant Engineers, and Executive Engineers.
3. Differential service experience requirements for diploma-holders and degree-holders for promotions.
4. Validity of the Departmental Promotion Committee (DPC) Note of 1971.
5. Interpretation of service rules regarding the eligibility for promotion.
6. Application of the principle of res judicata.

Issue-wise Detailed Analysis:

1. Transfer and Retransfer of SWD:
The SWD, initially part of MCD, was transferred to DDA in 1974 with a stipulation that only its employees would be considered for confirmation and promotions. It was re-transferred to MCD in 1978 and then back to DDA in 1980, again with the stipulation that it would remain a separate entity without merging with DDA.

2. Recruitment and Promotion Rules:
The DDA adopted CPWD's Recruitment Rules for Junior Engineers, Assistant Engineers, and Executive Engineers. Junior Engineer posts were meant for 100% direct recruitment, requiring a Diploma in Civil Engineering with two years' experience. Degree-holders could also apply without prior experience. Assistant Engineer posts were filled 50% by direct recruitment or deputation from degree-holders and 50% by promotion from Junior Engineers. For promotions, diploma-holders required eight years of service, while degree-holders needed three years. Promotion to Executive Engineer required eight years of service for degree-holders and ten years for diploma-holders.

3. Differential Service Experience Requirements:
The rules prescribed different service experiences for diploma-holders and degree-holders for promotions. This distinction was challenged but upheld by the Supreme Court in Roop Chand Adlakha v. Delhi Development Authority, which recognized the validity of different service requirements based on educational qualifications.

4. Validity of the DPC Note of 1971:
The DPC appended a Note in 1971 relaxing the rules for diploma-holders who acquired degrees, allowing them to be considered for promotion as Assistant Engineers. This Note was challenged and ultimately deemed ultra vires by the Full Bench of the Delhi High Court, as it violated statutory rules and was not approved by the DDA.

5. Interpretation of Service Rules:
The Supreme Court examined whether the three years' service experience required for promotion to Assistant Engineer should be counted from the date of obtaining the degree or include the service period prior to obtaining the degree. The Court concluded that the service experience required for promotion in the degree-holder quota must be as a degree-holder Junior Engineer. The service rendered as a diploma-holder cannot be substituted for the service rendered as a degree-holder.

6. Application of the Principle of Res Judicata:
The Full Bench of the Delhi High Court held that the principle of res judicata did not apply because a wrong interpretation of a statute that affects fundamental rights would render a decision nullity. Therefore, the earlier decisions based on misinterpretation did not attract the principle of res judicata.

Conclusion:
The appeals were allowed, and the impugned judgment of the High Court was set aside. The writ petitions were remitted back to the Division Bench of the High Court for reconsideration in light of the Supreme Court's interpretation. The Court emphasized that diploma-holder Junior Engineers who obtain a degree during service must complete three years of service after obtaining the degree to be eligible for promotion in the degree-holder quota.
