category as LPSA or UPSA during the relevant time. Perusal of Ext.P17 dated 1.6.1999 would show that Sri.P.V.Sidharthan was appointed by the Management under the UPSA category. His appointment under the said category has also been approved by the Assistant Educational Officer. The contention urged by the petitioner is that since he was teaching in LPSA, he was treated as the LPSA teacher, especially when the categorisation had taken place between LPSA and UPSA. But insofar as it is clear from the appointment order that his appointment was as UPSA which was approved by the Educational authorities, merely for the reason that he was teaching in LPSA section by itself will not indicate that his appointment was as LPSA. Under such circumstances, the learned single Judge was justified in placing reliance upon Ext.P17 and treating the Headmaster as coming under UPSA section.
