There is an interesting sentence in the post that shows why you want to ask actual lawyers, even if the law actually meant what one would think based on a common-sense reading of the text (it often doesn't) and you could read it (you often can't, because you might not know about a second law that also applies):

Lawyers don't just tell you how the law is interpreted, but also how it's applied in practice. Often, bad law is worked around by the legal system rather than fixing it, and while one could rightfully lament this, if your goal is to get something done rather than fix the country's legal system... ask a lawyer and you might find yourself unblocked, or be told about a way to avoid the issue, or at least have a better understanding how big the risk is in practice, allowing you to make an informed decision.
