Most of these legislative references are not to the Treaty text but rather to the "principles" of the Treaty. This is because the two texts of the Treaty have led to different understandings, and because of the need to apply the Treaty to present-day circumstances and issues.
Treaty principles interpret the Treaty as a whole, its intention and its spirit. In the 1994 Broadcasting Assets case (p. 513), Lord Woolf described the principles as "the underlying mutual obligations and responsibilities the Treaty places on the parties. They reflect the intention of the
Treaty as a whole and include, but are not confined to, the express terms of the Treaty."
