Supreme Court Judgments, Summarised

by Barrister Tahmidur Rahman | Nov 3, 2026

Summary

The petitioners, retired employees of the Bangladesh Water Development Board, joined between 1975 and 1984 under the Contributory Provident Fund (CPF) scheme and did not opt for the General Provident Fund (GPF) pension scheme when options were invited in 1986. Regulations 1(2)(ga) and 3(1)(ka) of the Board's 2000 pension regulations excluded employees who had not opted by 29.10.1986. Earlier writ petitions seeking conversion to GPF succeeded in the High Court Division, but the Appellate Division reversed them on 04.02.2020, noting that the regulations had not been challenged. The petitioners then challenged the regulations and the 1986 option instruction as retrospective and unlawful. The High Court Division held that res judicata applies to writ proceedings and that the petitioners could and ought to have challenged the regulations in the earlier petitions. As the relief sought was substantially the same as that refused by the Appellate Division, the petition was barred by constructive res judicata. The other issues were not decided and the Rule was discharged.

Issues

  1. Q1

    Whether a writ petition challenging the vires of pension regulations was barred by constructive res judicata after earlier writ petitions seeking conversion from CPF to GPF had failed before the Appellate Division.

  2. Q2

    Whether the principle of res judicata applies to writ proceedings.

Key points

  • The bar of res judicata applies to writ proceedings on the general principle that there should be an end to litigation and no one should be vexed twice on the same subject matter.
  • Under Explanation IV to section 11 of the Code of Civil Procedure, a matter which might and ought to have been raised in the earlier proceeding is deemed to have been directly and substantially in issue.
  • Having had every opportunity to challenge the vires of the regulations in the earlier writ petitions, the petitioners could not raise that challenge in a later petition seeking the same relief.
  • A change in the form of challenge does not alter the substance of the relief, which had already been refused by the Appellate Division.
  • As the petition was barred by constructive res judicata, the Court did not examine the remaining issues.

The change in the form of the challenge in the present writ petition, therefore, cannot by itself alter the substance of the relief sought for.
