Meet Lex Maritima – the first codification of universal Maritime Law Principles by CMI

Maritime law, a distinct body of law governing maritime questions and offenses, is deeply rooted in historical practices and modern international agreements..

Maritime law founded on globally accepted basic principles, common customs, and generally accepted contractual clauses have always played a crucial role in global trade, given that approximately 80-90% of the world’s trade is carried by sea..

Despite its importance, however, a codification of the universally accepted principles that govern maritime affairs has been missing..

Comité Maritime International (CMI), the leading global organization dedicated to the unification of maritime law, has taken a significant step forward to address this gap by consolidating these principles into a coherent and accessible framework termed “Lex Maritima“..

The CMI considers the Lex Maritima to be the first elaborate instrument in this space and the maritime equivalent of the Lex Mercatoria (Latin for Merchant Law), a set of commercial laws widely accepted across different jurisdictions since the medieval ages..

By providing a common foundation, the CMI Lex Maritima aims to harmonize maritime law practices globally, thereby enhancing legal certainty and predictability for maritime stakeholders..

This pioneering document is a comprehensive articulation of 5 rules and 25 principles principles of maritime law, aiming to provide clarity, facilitate education, and promote international uniformity in this specialized legal field..

Preliminary Rules and Definitions

    1. Rule 1 – Objective
      The primary goal of the CMI Lex Maritima is to elucidate the foundational principles of maritime law, promoting its specificities and contributing to international uniformity.. This clarity helps in better understanding and application of maritime law globally..
    2. Rule 2 – Definitions
      Key terms are defined to ensure consistency and clarity.. For example, ‘ship’ includes all types of seagoing vessels, and ‘positive maritime law’ encompasses the rules of public or private maritime law that apply to maritime matters..
    3. Rule 3 – Scope Ratione Navis
      These principles apply to all ships, with specific exceptions as outlined in the positive maritime law.. This ensures broad applicability while respecting particular legal nuances..
    4. Rule 4 – Status of Principles
      The principles are meant to supplement rather than override positive maritime law, providing a common international foundation that supports existing legal frameworks..
    5. Rule 5 – Application of Principles
      These principles should be applied in cases where positive maritime law refers to general principles of maritime law, or when parties to a contract incorporate them, ensuring their practical relevance and utility..

Sources of Maritime Law

    1. Principle 1 – Interpretation of Maritime Law
      This principle encourages uniform interpretation of maritime law, which facilitates global maritime shipping and trade.. It underscores the importance of these principles in interpreting positive maritime law..
    2. Principle 2 – Maritime Custom

    2. Principle 4 – The Law Governing Property Interests
      Property interests in ships and maritime mortgages are governed by the law of the State where the ship is registered, ensuring clear and consistent legal treatment..

    5. Principle 10 – Joint and Vicarious Liability of Shipowner and Ship Operator
      This principle establishes joint and vicarious liability for shipowners and operators, ensuring accountability for actions undertaken during the ship’s operation..
    6. Principle 11 – General Tonnage Limitation

Maritime Contracts

    1. Principle 13 – Freedom of Maritime Contract
      Parties are free to enter into maritime contracts, provided they comply with mandatory international and national laws, ensuring flexibility within a regulated framework..
    2. Principle 14 – Bareboat Charterparty
      A bareboat charter involves hiring a ship without a crew, with the charterer assuming full control and responsibility, reflecting common maritime leasing practices..
    3. Principle 15 – Time Charterparty
      Under a time charter, the shipowner provides the crew and maintains the vessel, while the charterer directs its commercial use for a specified period..
    4. Principle 16 – Voyage Charterparty
      A voyage charter involves hiring a ship for a specific voyage, with the shipowner responsible for navigation and maintenance, common in cargo transportation..

      Salvage operations are governed by principles ensuring fair compensation for salvors who save lives or property at sea, encouraging such life-saving efforts..
    3. Principle 21 – General Average
      In maritime emergencies, general average principles allow for equitable sharing of losses among all parties involved in a voyage, promoting fairness in risk management..
    4. Principle 22 – Wreck Removal
      Shipowners are responsible for the removal of wrecks that pose hazards to navigation or the environment, ensuring safety and environmental protection..

Maritime Securities and Time Bars

    1. Principle 23 – Preferential Rights
      Certain maritime claims have preferential rights, ensuring the priority of claims such as crew wages and salvage, protecting vital interests..
    2. Principle 24 – Immobilisation of Ships
