The most significant exception is piracy. Piracy is considered a crime against all humanity (hostis humani generis). Therefore, any state can seize a pirate ship or aircraft on the High Seas, arrest the pirates, and prosecute them under its own laws, regardless of the pirates' nationality or the flag of the pirate vessel. This universal jurisdiction is crucial because piracy threatens global maritime safety and trade, and relying solely on a flag state's jurisdiction would make enforcement nearly impossible.

For India, the "no sovereignty" principle means its naval vessels, research ships, or commercial vessels can operate freely on the High Seas without needing permission from any other state. India cannot claim any part of the High Seas as its own, nor can any other nation claim sovereignty over areas where India operates. This ensures India's freedom of navigation for trade, strategic deployments, and scientific exploration, but also means India has a shared responsibility for conservation and peaceful use, without exclusive rights to resources or control over other nations' legitimate activities.

Critics argue that the "freedom of fishing" and "freedom of scientific research" on the High Seas, while fundamental, have historically led to overexploitation of marine resources and inadequate environmental protection. The primary issue is the lack of a strong, unified governance mechanism.

• •Overfishing: Individual states prioritize their economic interests, leading to unsustainable fishing practices and depletion of fish stocks, as enforcement is difficult.
• •Environmental Degradation: Pollution (plastic, noise, chemical) and habitat destruction often go unchecked due to fragmented jurisdiction and lack of a single enforcement body.
• •Deep Seabed Mining: The legal framework for deep seabed mining in areas beyond national jurisdiction is still evolving, raising concerns about potential irreversible environmental damage.
• •Proposed Solutions: Critics advocate for a stronger international body with enforcement powers, a more robust and binding agreement on biodiversity beyond national jurisdiction (BBNJ Agreement), and greater cooperation among states for marine protected areas and sustainable resource management.

The IRIS Dena incident highlighted that there are no formally defined "war zones" in the maritime domain, meaning conflicts can erupt in any international waters, including the High Seas or EEZs. This challenges the traditional notion of geographically confined conflict areas. While the High Seas are governed by UNCLOS and the UN Charter (prohibiting force, allowing self-defense), the incident showed the complexities of applying these rules when a non-state actor (or a state acting outside declared war) uses force. It underscored that even in peacetime, geopolitical tensions can lead to military actions in areas beyond territorial waters, necessitating a careful interpretation of Article 2(4) and Article 51 of the UN Charter regarding the use of force and self-defense.

While states enjoy freedoms like navigation, overflight, and fishing on the High Seas, these are not absolute and come with significant obligations:

• •Conservation of Living Resources: States have a duty to cooperate in the conservation and management of living resources, preventing overexploitation and ensuring sustainability. This is crucial for fishing freedom.
• •Protection of Marine Environment: States must take measures to prevent, reduce, and control pollution of the marine environment from any source.
• •Cooperation in Suppressing Illicit Activities: This includes cooperating to suppress piracy, slave trade, unauthorized broadcasting, and drug trafficking.
• •Assistance to Persons in Distress: Ships are obligated to render assistance to any person found at sea in danger of being lost.
• •Peaceful Uses: All activities on the High Seas must be for peaceful purposes.

The High Seas are open to all states, whether coastal or land-locked. This means landlocked countries, despite lacking a coastline, have the right to use these waters for navigation, overflight, and other legitimate uses. This provision is crucial for global equity because it ensures that landlocked states can access global maritime trade and resources through agreements with coastal states (for transit access to ports). Without this, they would be entirely dependent on the goodwill of neighboring coastal states, severely limiting their economic development and international engagement. It upholds the principle that the oceans are a common heritage for all humanity.

India strongly upholds the principle of freedom of navigation and overflight on the High Seas, as it is crucial for its trade, energy security, and naval deployments in the Indo-Pacific. India actively participates in multilateral naval exercises like MILAN-2026 to reinforce these principles and ensure open sea lanes. However, India also balances this with its security concerns, particularly regarding illegal activities, maritime terrorism, and challenges to its EEZ. It advocates for a rules-based order under UNCLOS, promoting cooperation for resource conservation and environmental protection, while also strengthening its own naval capabilities to protect its interests and contribute to regional stability. India seeks to ensure that the High Seas remain free and open, but also secure and sustainably managed.

Part VII of UNCLOS is specifically dedicated to the High Seas, outlining the freedoms and duties of states. Articles 87-115 are particularly relevant. Article 87 lists the freedoms (navigation, overflight, fishing, etc.), while subsequent articles detail obligations like conservation of living resources (Article 117-120) and cooperation in suppressing illicit traffic (Article 108-110). A common misconception is that UNCLOS provides a detailed enforcement mechanism for all High Seas activities. While it sets the framework, actual enforcement often relies on flag states or specific international agreements, and UNCLOS itself doesn't create a global High Seas police force.

The primary limitation stems from the "no sovereignty" principle itself – while it prevents monopolization, it also creates a governance vacuum.

• •Fragmented Jurisdiction: Enforcement largely depends on flag states, leading to varying standards and difficulties in prosecuting violations (e.g., illegal fishing, pollution) by vessels from uncooperative states.
• •Resource Exploitation: The "freedom of fishing" has often led to overfishing due to inadequate international cooperation and enforcement of conservation measures.
• •Emerging Issues: UNCLOS was drafted before issues like deep-sea bioprospecting, large-scale marine geoengineering, or the full extent of climate change impacts were understood. The current framework struggles to effectively regulate these new activities.
• •Lack of Central Authority: There is no single international body with overarching authority to manage or enforce laws across the entire High Seas, making coordinated action difficult.

The BBNJ Agreement (also known as the High Seas Treaty) is a landmark agreement under UNCLOS that aims to ensure the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction.

• •Key Provisions: It proposes establishing marine protected areas (MPAs) on the High Seas, regulating marine genetic resources (MGRs) and benefit-sharing, conducting environmental impact assessments (EIAs) for activities in these areas, and building capacity and transferring marine technology to developing countries.
• •Strengthening Governance: It creates a framework for coordinated action and decision-making, moving beyond the fragmented approach.
• •Challenges: Implementation will be complex due to the vastness of the High Seas, the need for widespread ratification, securing adequate funding, and overcoming potential resistance from states prioritizing short-term economic gains over long-term conservation. Ensuring effective enforcement across diverse national interests will be a significant hurdle.
