Montreal Protocol No. 4 introduced several critical changes to aviation law:

While MP4 was a major step forward, it was eventually superseded by the Montreal Convention of 1999 (MC99), which came into force on November 4, 2003. MC99 consolidated the various protocols (including MP4) into a single, unified treaty that currently governs most international flights today. 4. Relevance in Aviation Insurance 41975mp4

specifically targeted the transport of goods (cargo). Montreal Protocol No

: It replaced the "Gold Clause" (SDRs) for calculating compensation, ensuring more stable and predictable financial recovery for cargo loss or damage. 3. Transition to the Montreal Convention (1999) In the insurance industry

: Unlike earlier systems that allowed carriers to avoid liability by proving they took "all necessary measures," MP4 established a system of strict liability . The carrier is liable for damage or loss to cargo regardless of fault, with only a few specific exceptions (such as inherent defect in the cargo or an act of war).

The international legal framework for aviation began with the Warsaw Convention of 1929 , which established uniform rules for passenger and cargo liability. By the 1970s, many of these rules were outdated. In September 1975, a series of "Additional Protocols" were signed in Montreal to update this system.

In the insurance industry, "1975 MP4" is still referenced when discussing historical liability frameworks or policies that cover operations in countries that have not yet ratified the 1999 Montreal Convention. It remains a cornerstone for understanding the evolution of aviation risk management and legal disputes involving international air carriage. US Manual of International Air Carriage
