Is it acceptable for a free license to limit the use of whatever it covers to lawful purposes?
I can only draw a parallel to Free Software here.
Freedom number 0 includes that a Free Software license must allow the use of a program for any purpose. Prosecution for breaking national law is of course not restricted by that. However in this case it is clearly the license putting limits on the purpose. Personally I would see a problem with this, even if the clause were purely tautological (which it is not).
The reason why this clause is included, is probably to ensure compliance with Danish law beyond national borders. For people outside of Danish jurisdiction this constitutes an arbitrary cut back of their freedom to use the software (if we were speaking of software). Within the jurisdiction of Denmark the clause would appear to be mostly superfluous.
I cannot tell, how this applies to questions of open data. If there is an open data definition, which ensures similar freedoms, then you have a path of reasoning here. It may not be easy to convince the government agency to give up this clause. I suspect they intend to prevent circumvention of national data protection laws.
