In the Czech republic, laws belong to public domain according to the copyright law, §3 a) https://www.zakonyprolidi.cz/cs/2000-121
This is not specified nor linked on the site where laws can be downloaded,so i marked it as not openly licensed. But after reading this discussion, I think the laws should be marked as openly licensed.
Also, amendments of the law are not provided separately but already integrated in the actual law that is available. What is available independently are not the approved amendments but transitional enactments.
Also, I spoke with people who work with this data on regular basis and was told, that the automated usage is very complicated, therefore question B9 should be marked as 1 (extensive effort required).https://discuss.okfn.org/t/open-license-requirements/4035/7
