So, if a letter or document that nominally or presumably conveys the signer's "intent" or intention to buy, is essentially meaningless and worthless in legal terms, and is not binding on the signer or anyone, and CANNOT be enforced on him, then why would a respectable crude buyer, in the first place, want to waste its precious time and resources (or that of its expensive lawyers) to engage in such a fruitless exercise for the benefit of a seller? Especially for an unknown or obscure seller?
The long and short of the story, is that the court, after scrutinizing not only the Memorandum, but also the wordings of the press releases and other documents that Getty Oil and Pennzoil had issued over the course of their dealings, found Getty Oil to be "in breach" of the Memorandum of Agreement _ the document the parties had viewed as a letter of intent. Thus, a document (the letter of intent) that the parties had started out viewing as non_binding and unenforceable, had changed from being that, to being a final agreement! Pennzoil, on the other hand, ended up with บǒ billion (later settled for ū billion) from Texaco for interfering in its deal with Getty Oil.
