If you consult Minnesota's legal materials online, cite them in a way that makes that clear. A citation to online material should include three elements:
the ordinary, official citation (see "How do I cite Minnesota's printed legal sources?")
the word "online." (You don't need to include the full URL.)
the access date, which is the latest date when the text appeared online in the form you cite.
For example, a complete citation of Minnesota Statutes, section 345.05 consulted online looks like this:
Minnesota Statutes 2014, section 345.05, online. Accessed November 17, 2014.
