No, any court can decide if the law is applied correctly or decide that a law is unconstitutional -- in fact, the lowest level of court can overturn any law. They are, however, required to apply the law correctly, including follow precedent set by any courts superior to them. Normally appeals courts only handle the question of whether the lower court applied the law correctly, and assume that the lower court interpreted the facts right. This is because normally (there are a few VERY rare exceptions) it is not legally permitted to appeal on the grounds that the court or the jury got the facts wrong... only on the grounds that the law was applied incorrectly.
