Bilateral treaties of equal validity in two languages can lack any agreed common version.

Evidence

A second example is the treaty of friendship signed in 1971 between the Soviet Union and the United Arab Republic. According to the text of the treaty, it was drawn up in two languages—Russian and Arabic, of equal validity. Unlike many other treaties, this has no agreed common version. Both Moscow and Cairo published English translations, but they are markedly different. We do not know in what language the treaty was negotiated and agreed. It may have been Russian or Arabic, with extensive use of interpreters all the way. It cannot have been English, since the Moscow English text is clearly translated from the Russian and the Cairo English text is clearly translated from the Arabic. There are a number of significant differences between them. — Bernard Lewis, From Babel to Dragomans, 198

• QUESTION: How do disputes over such a treaty ever get resolved when neither side can agree on a canonical text? This seems like a standing procedural crisis.
