Three golden rules for giving code reviews, from this article on sofiacole.com: 1) Ask questions rather than give statements, 2) Limit personal preference, and 3) Check its purpose.
Regarding the second rule, I don’t know anything about it, as I’ve never been on a team that allowed “personal preference.” Each team (or company) agreed on coding standards, and used them.
