True, one should never jump to conclusions, especially when there is only sparse information provided. For example, the author states that her defense team has appealed to a higher court yet he/she does not elaborate on the reason why. Now in retrospect and after re-reading the article, I think that little particular is quite important and it makes me curious, (from the journalistic viewpoint) why does the PPA feel rather confident that the law is on her side: "The complaint further states that the Waltons own intellectual property rights to the photos (they don't). The fact is, under federal law, photographers own the copyrights to their own works." ?
Actually it does state why its going to a higher court, maybe you miss this important fact, but the reason is that the issues regarding photographers rights are covered under federal guidelines not state guidelines so the attorneys for the defendant wanted to escalate the issue to a federal court so that their defense would hold up being that it was a federal law.
