Statutes in the USA have even shorter timescales than that, but it doesn't stop the public bodies doing all sorts of end-run-arounds to avoid it.

And when they do violate your timescales, whatchagonnadoaboutit? It's technically a criminal offense in many jurisdictions, but no prosecutor in their right mind is going to bring the case. Which means you have to litigate it in civil courts and now you're four years deep and you've taken 73 days out of your work to attend court dates that end in continuances.

[The worst thing is, in Illinois it is a "civil penalty" for violating the FOIA; one State's Attorney was honest with me - "I don't care when I lose, we just write out a check to ourselves. Out one account, into the other!"]
