Katchatheevu: History and Legal Status
Katchatheevu is a small uninhabited island (approximately 285 acres) in the Palk Strait, situated between India and Sri Lanka. It was ceded to Sri Lanka by India under the 1974 Indo-Sri Lanka Maritime Agreement, signed between PM Indira Gandhi and PM Sirimavo Bandaranaike. A 1976 agreement further defined the International Maritime Boundary Line (IMBL). While the agreements allow Indian fishermen to visit the island for the St. Anthony's Church festival and to dry their nets, they do not permit fishing in Sri Lankan waters. The Tamil Nadu government has repeatedly demanded the return of Katchatheevu, and the issue has been raised in the Supreme Court as a challenge to the 1974 agreement.
- Katchatheevu island size: approximately 285 acres
- Ceded to Sri Lanka: 1974 Indo-Sri Lanka Maritime Agreement (PM Indira Gandhi – PM Sirimavo Bandaranaike)
- IMBL (International Maritime Boundary Line): Defined by 1976 agreement
- Rights retained for Indian fishermen: Visit for church festival; dry nets on island shore; no fishing rights
- Tamil Nadu SC petition: Tamil Nadu government filed petition challenging the 1974 cession as unconstitutional
- Location: Palk Strait, between Rameswaram (India) and Jaffna (Sri Lanka)
Connection to this news: The arrests near Katchatheevu reflect the fundamental tension created by the 1974 cession — Indian fishermen who traditionally fished these waters for generations now cross into Sri Lankan-claimed territory, leading to recurrent arrests that have persisted for decades.
India-Sri Lanka Maritime Boundary and the IMBL
The International Maritime Boundary Line (IMBL) between India and Sri Lanka divides the Palk Strait, Gulf of Mannar, and the waters around Katchatheevu. The narrow strait — only 64 km at its widest between India and Sri Lanka — makes it extremely easy for fishing vessels to inadvertently (or deliberately) cross into the other country's Exclusive Economic Zone (EEZ). Sri Lanka's Exclusive Economic Zone (EEZ) under UNCLOS extends 200 nautical miles from its coast. The traditional fishing grounds used by Tamil Nadu fishermen in the Palk Strait fall substantially within Sri Lanka's EEZ, creating a structural tension between historical fishing practice and modern maritime law.
- Palk Strait width: approximately 64-137 km
- India-Sri Lanka IMBL: Defined by 1974 and 1976 agreements
- Sri Lanka's EEZ: 200 nautical miles under UNCLOS
- Key fishing communities affected: Rameswaram, Nagapattinam, Pamban (Tamil Nadu)
- Gear dispute: Sri Lanka (and TN fishermen's associations) object to use of bottom-trawling nets; Indian fishermen from Rameswaram mostly use trawlers
Connection to this news: The arrest of Rameswaram fishermen near Katchatheevu is a microcosm of the larger maritime boundary and livelihood conflict — where international law, historical fishing rights, and neighbourhood diplomacy intersect.
Fishermen Issue in India-Sri Lanka Bilateral Relations
The arrest of Tamil Nadu fishermen by Sri Lanka is a perennial flashpoint in India-Sri Lanka bilateral relations, typically affecting relations between the two governments, the Tamil diaspora sentiments, and domestic Tamil Nadu politics. India has repeatedly raised the issue with Sri Lanka at the highest levels. The Joint Working Group on Fisheries (established under the India-Sri Lanka Joint Committee framework) meets periodically to address these concerns. Sri Lanka's position is that Indian fishermen violate its sovereign territorial waters and damage marine ecosystems through bottom-trawling.
- Joint Working Group on Fisheries: Established under India-Sri Lanka Joint Committee; meets periodically
- India's diplomatic approach: Raise through consular channels; seek early release through MEA and High Commission
- Sri Lanka's argument: Trawler fishing destroys seabeds; Indian trawlers operating in its EEZ are violating sovereignty
- Tamil Nadu Chief Minister's role: Typically writes to MEA and Prime Minister demanding action (strong domestic political pressure)
- Fishermen releases: Usually negotiated through diplomatic channels; typically take weeks to months
Connection to this news: The arrests near Katchatheevu — in the context of 116 fishermen already in Sri Lankan jails — represent a major humanitarian and diplomatic challenge, and reflect the ongoing failure of bilateral mechanisms to find a durable solution to this recurrent problem.
