CLAT GK + INTERNATIONAL SECURITY LAW & MARITIME LAW
Britain and Norway have conducted a weeklong joint military operation to deter Russian spy submarines suspected of operating near undersea cables in the North Atlantic. UK Defence Secretary John Healey revealed the operation at a press conference, while Norway’s defence minister warned that damage to undersea cables “will not be tolerated.” The operation was coordinated by NATO’s Allied Maritime Command (MARCOM), reflecting growing concerns across the alliance about Russian espionage targeting critical maritime infrastructure. Russia has dismissed the claims as baseless.
Why This Matters for CLAT 2027
This story sits at the intersection of several important legal concepts: maritime law (UNCLOS), collective defence (NATO Article 5), hybrid warfare, and sovereignty over maritime infrastructure. CLAT’s GK section frequently tests knowledge of international organisations and treaties, while Legal Reasoning passages may draw from maritime law or international security scenarios. Understanding the legal framework governing EEZs, continental shelves, and submarine operations is essential.
Constitutional & Legal Framework
- UNCLOS Part V (Articles 55-75): Establishes the EEZ regime — coastal states have sovereign rights over natural resources and jurisdiction over marine installations including cables and pipelines
- UNCLOS Article 113: Requires states to make it a punishable offence for any person to break or injure submarine cables or pipelines
- NATO Treaty Article 5: An armed attack against one or more NATO members shall be considered an attack against all — collective self-defence
- UN Charter Article 51: Preserves the right of self-defence until the Security Council takes necessary measures
- London Naval Treaty (1930) & 1936 Protocol: Established rules for submarine warfare, requiring submarines to follow prize rules for merchant vessels
- Continental Shelf (UNCLOS Article 76): Extends up to 350nm; coastal state has sovereign rights over resources and installations
The Undersea Cable Threat
Undersea cables carry approximately 95% of the world’s intercontinental data traffic. Damage to these cables — whether through espionage, sabotage, or military action — could cripple communications, financial systems, and military command networks. In recent years, NATO countries have documented multiple incidents of Russian submarine and research vessel activity near critical undersea infrastructure in the North Atlantic, Baltic Sea, and Arctic regions.
The legal status of undersea cables is governed by UNCLOS. Article 113 requires all states to make it a punishable offence to wilfully or negligently break or injure submarine cables. The 1884 Convention for the Protection of Submarine Telegraph Cables — one of the oldest international agreements still in force — further reinforces this protection. However, enforcement remains challenging, particularly when the threat comes from state actors operating submarines in international waters or foreign EEZs.
NATO Article 5 and the Grey Zone Problem
NATO Article 5 — the cornerstone of the alliance’s collective defence — was designed for conventional armed attacks. The challenge of hybrid warfare (combining conventional, irregular, cyber, and covert methods) is that it often falls below the threshold of Article 5. Cutting or tapping undersea cables could be an act of war, espionage, or criminal sabotage depending on the circumstances, making the legal response complicated.
The UK-Norway operation represents a deterrent approach — demonstrating capability and willingness to detect and respond to submarine threats without necessarily invoking Article 5. This “deterrence by detection” strategy is becoming a key element of NATO’s response to hybrid maritime threats.
CLAT Exam Angle
- GK/Current Affairs: NATO structure, Article 5, MARCOM, UK-Norway defence cooperation, hybrid warfare concept
- Legal Reasoning: UNCLOS provisions on EEZ jurisdiction, protection of submarine cables, maritime sovereignty issues
- International Law: Distinction between espionage (not prohibited under international law), sabotage (violation of UNCLOS), and armed attack (Article 5 trigger)
- Maritime Zones: Territorial sea (12nm), Contiguous zone (24nm), EEZ (200nm), Continental shelf (up to 350nm)
- Key Question: At what point does submarine espionage near infrastructure become an “armed attack” under Article 5?
