A suggestion, there may be information in the World Legal Institute Databases if there have been cases in the Courts systems.
unfortunately I'm not on a computer at the moment to look it up but there should be cases internationally tucked in there that may help in general terms - use keywords like Airbnb and your local country/ locations names.
You may also like to scan through Google under "news" as ongoing information about these laws and discussions are in there.
When you find cases with names in you may like to further use then to follow up directly with those people as addresses and personal profiles are frequently online, subject to ones own digital footprints.
Hope that helps.
Please let us know how you get on.
It may be an idea to see if you have any local Residents Association groups that hold meetings in your region as such topics are discussed at there meetings from time to time.
