can someone be a considered authority without being an expert.
edit:
I am using authority from the example in wikipedia
"One example of the use of the appeal to authority in science dates to 1923,[20] when leading American zoologist Theophilus Painter declared, based on poor data and conflicting observations he had made,[21][22] that humans had 24 pairs of chromosomes. From the 1920s until 1956,[23] scientists propagated this "fact" based on Painter's authority"
Painter presumably was an expert. So not sure why you are saying why its ok if the person is an expert.
Some political appointees could probably be considered an authority by title and not a subject expert. That might hold true for some ambassadors. I guess it really depends on what exact definition of authority you are using.
Parents, older siblings, managers/bosses, almost any TV personality. Also you might have someone who has a profession in the topic at hand, but isn't an expert. Like your older cousin who is a first-year Comp Sci major probably isn't the hacking/security expert you should be appealing to.
