I think what Abdul said is right that you don't want sensitive validations done on the client. And you should keep in mind that when you send data to the server you often should validate it again to make sure someone hasn't spoofed a client to avoid your validation logic.
AS3 is pretty fast now so you can do more complex validation without too much of a performance hit. So unfortunately I think "it depends" remains operative.

Our current approach is to perform basic data validation (valid values for each field) on the client side and invoke server-side objects to perform more thorough validation such as relational edits(e.g. "if field x > 100, field y must have value AA"). However, I'm wondering whether an approach that favors more client-side validation would be better. Something like "validate on the client side as long as no call to the server is required to retrieve additional data or access external services." The answer, I imagine, is "it depends." But I'd be interested to know what factors to consider and what guidelines others are using for their Flex data capture applications.
