Welcome to the reality of Tunisia.
Let me elaborate a bit more on how Tunisia works:
There are laws in Tunisia. They are being proposed (some people then think they are in place already), then the parliament discusses them (more people will think they are in place) and then voted upon (now all people think they are in place). And then the president has to sign them and THEN they are in place. However there have been quite a few laws that rested on the president desk for many years and were then signed, rejected or silently discarded.
Then we have the citizens. Some follow the law, some don't. Some don't and pay bribe to the authorities to keep not doing it. And only when they cannot bring up the money for more bribes or the case goes into the press, the next higher authorities will act to enforce the law - unless they are bribed, see above. You will, for example, see in Tunisia sometimes caterpillars turning up and demolishing stalls, shops and even whole houses ... having been build illegally 2, 5 or 10 years ago. When buildings are being built, sometimes a lorry turns up, people come out of it and start hammering a hole into the wall of the building - which is the tunisian way of announcing a "condemned" building. Then they leave and take all work utensils they can find in this building with them.
Then we have the police and administration. They have to enforce the law ... if they know about it. Sometimes it takes days, sometimes weeks, and sometimes a new law will never reach them officially, and if it didn't, they won't enforce it. But let's assume it did reach them, then they may start to interpret it and have very diverging views on what it really says - which leads to a law being enforced or not, or being put into the court system for the next 2, 5 or 10 years to come. And I did not even mention bribes...
Sometimes they simply invent laws - menaing they pretend there is a law, but there isn't. This can be fixed by paying a bribe - or by putting the case to higher authorities or into the court system, see above.
And finally, there is the court system. Apart from obious things, like bribes or following the law, there comes now also the issue of "morality" into play, because Tunisia is, after all, a state of muslim values. And so the court may enforce the law, or not, or put the case back into the court system where it can stay another 2, 5 or 10 years - or forever, when, for example, the constitution is affected. Because the parliament has, in multiple years, not yet agreed on judges for the court of constitution, therefore, this court simply does not exist yet, although the constitution has been in place for some years already...
Like I said: Welcome to the reality of Tunisia!
