Some logical fallacies are easy to catch, but that particular one can be
difficult. It can be a matter of opinion as to whether an assertion is
falls in that category or not. See:

http://www.nizkor.org/features/fallacies/appeal-to-authority.html

The discussion here is longer and more nuanced that for other fallacies.
Here are some quotes from it:


. . . This fallacy is committed when the person in question is not a
legitimate authority on the subject. More formally, if person A is not
qualified to make reliable claims in subject S, then the argument will be
fallacious.

This sort of reasoning is fallacious when the person in question is not an
expert. In such cases the reasoning is flawed because the fact that an
unqualified person makes a claim does not provide any justification for the
claim. The claim could be true, but the fact that an unqualified person
made the claim does not provide any rational reason to accept the claim as
true. . . .

. . . Since this sort of reasoning is fallacious only when the person is
not a legitimate authority in a particular context, it is necessary to
provide some acceptable standards of assessment. The following standards
are widely accepted:

1. The person has sufficient expertise in the subject matter in question.

Claims made by a person who lacks the needed degree of expertise to make a
reliable claim will, obviously, not be well supported. In contrast, claims
made by a person with the needed degree of expertise will be supported by
the person's reliability in the area.

Determining whether or not a person has the needed degree of expertise can
often be very difficult. In academic fields (such as philosophy,
engineering, history, etc.), the person's formal education, academic
performance, publications, membership in professional societies, papers
presented, awards won and so forth can all be reliable indicators of
expertise. . . .


2. The claim being made by the person is within her area(s) of expertise.

If a person makes a claim about some subject outside of his area(s)
of expertise, then the person is not an expert in that context. Hence, the
claim in question is not backed by the required degree of expertise and is
not reliable.

It is very important to remember that because of the vast scope of human
knowledge and skill it is simply not possible for one person to be an
expert on everything. Hence, experts will only be true experts in respect
to certain subject areas. In most other areas they will have little or no
expertise. Thus, it is important to determine what subject area a claim
falls under. . . .
