No, the Anglo-Saxon law (US, UK, etc.) is different and makes no assumptions outside of the contract; the contract is applied verbatim as written, and when something is missing, it is not part of the contract. In Europe on the other hand the contract is just one piece of the puzzle and the judge can add, remove or modify clauses in search of the true pary intentions; in case of conflicting elements, the judge may refer to what is applicable under the usual rules for such contracts and even change the contract type. That's why Tivoization with GPL v2 is unquestionably legal in USA, but there is still a certain legal uncertainty in Europe, because there is no supreme court decision.
