In this case, according to the description of the photo which we were given and interpreting the summary of the law which we were shown, I think it's pretty clear that the photo lab AND the police applied that law incorrectly.
Incorrect, negligent and/or discriminatory application of a law against one person for arbitrary reasons is a redressable offense.
Yes, this is Australian law but I'll say it again. It doesn't matter if you're in Adelaide or Albuquerque. You can't just make up laws and you can't decide when to apply them. You have to go by what is written.
According to what I read, the laws in question were interpreted incorrectly, applied incorrectly and, in my opinion, they were applied NEGLIGENTLY.
