Kaushal Kishore Singh vs Dy. Director Of Education And Ors.

The Supreme Court upheld the decision of the Allahabad High Court regarding the promotion of respondent No. 4 to the post of Lecturer, emphasizing that seniority in one grade does not dictate seniority in another. The Court noted that the appellant's claim of seniority in the LT Grade was recognized, but the promotion of respondent No. 4 was valid as it had not been annulled by any competent authority or court. The Court concluded that the appellant's challenge to the promotion of respondent No. 4 was not sustainable under the existing regulations and legal framework.
