Supposedly law-neutral

When “supposedly” is in front of a statement, it can mean without truth, or regarded as truth, but without actual knowledge.

She was supposedly his first love, but everyone knew how he felt about Mary.

Supposely he had a fortune, and was going to invest in another business.

It’s difficult to know what your phrase means without some context. Can you write the entire sentence?

Hey,
Thanks for your answer. Of course I can post the whole sentence: At the same time this libertarian term of freedom typically is used as supposedly law-neutral term that suggests freedom as the absence of enforcement. So you see that the term of freedom has its roots in a libertarian view. Thus to say that the freedom of the individual person has its roots in the personal property rights. https://en.wikipedia.org/wiki/Libertarianism#Right-libertarianism offers a brief description of the concept.
