Taking the story at face value, the issue isn't necessarily delegation. If the C-suite is making a decision and one of their primary people (CTO in this case) is absent, it almost doesn't matter who he delegates to. The delegated individual is not their peer, so whatever they say will be discounted. I've been in that situation (as the delegated individual) several times. It's frustrating. Even if they respect you, you don't get a vote in the final decision.
