In a reply affidavit filed before the court, the Centre said "Under the agreements of 1974 and 1976, Indian fishermen and pilgrims will enjoy access to Katchatheevu and will not be required by Sri Lanka to obtain travel documents or visas for these purposes. The right of access is not understood to cover fishing rights around the island to Indian fishermen."
Disputing the claim, the Centre said the boundary between the two countries had already been clearly delineated and it would not allow Indian fishermen to cross over and exploit the marine resources in the waters of another country.
It said the fishermen could rest, dry their nets and attend the annual St Antony's festival in Katchatheevu, an islet ceded by India to Sri Lanka.
A bench, comprising acting Chief Justice Satish K Agnihotri and Justice M M Sundresh, adjourned the matter by two weeks for further hearing.
