You're inferring what's pretty explicit in the contract between AZ and EU - there's no mention of anything about being last for not being part in the development process. You're just making up something to try to justify it, where it says no where that deal. AZ was the one that said it will sell at price of cost. AZ was the one that agreed that it would fulfill EU orders from outside EU production. AZ was the one who agreed that no other contract would compromise EU supply. If AZ had to take into consideration contract celebration dates, development costs participation, and what ever else you're saying that makes you claim that AZ is entitled to breach the contract - then THEY SHOULD HAVE PLACED THAT IN THE CONTRACT. Maybe EU would have looked at other alternatives, or made the required adjustments. AZ has different contracts with different countries and they don't want to disclose that some contracts are being prioritized over others, and putting themselves on the breach of EU contract.
