It is a law though. The mistake is in thinking that means it will always hold true or is necessarily "correct".
As wikipedia nicely puts it:
Scientific laws:
1) summarize a large collection of facts determined by experiment into a single statement,
2) can usually be formulated mathematically as one or several statements or equation, or at least stated in a single sentence, so that it can be used to predict the outcome of an experiment, given the initial, boundary, and other physical conditions of the processes which take place,
3) are strongly supported by empirical evidence - they are scientific knowledge that experiments have repeatedly verified (and never falsified). Their accuracy does not change when new theories are worked out, but rather the scope of application, since the equation (if any) representing the law does not change. As with other scientific knowledge, they do not have absolute certainty like mathematical theorems or identities, and it is always possible for a law to be overturned by future observations.
"Law" is not a stronger form of "theory", as is popularly believed.
Now granted, it is not a particularly good law. Strictly speaking it is bad science, but a law it is nevertheless.
