T'Pring was dishonest. T'Pau was dishonest. One can quibble about whether they "lied," but if one can deceive or mislead then one can lie.
Strictly within the context of "Amok Time", I disagree. All of these characters were playing parts in a ritual that wrote their actions. No one had any lies to tell or omit that I can divine.
This is ancient ritual, there aren't any ethics involved. The players must play their roles or be punished, even killed outright.
