I know that they slowly made the EMH an actual member of the crew and grew the character, but if it came down to it could he have formally relieved Janeway of duty? Since he wasn't a ranking officer would he have been able to make it work officially? For example, if he thought that Janeway was unfit for duty due to having a severe concussion and he said she was relieved would she be bound by that order or is it a suggestion from what is passing as chief medical officer?
