Below is one of Judge Watts statements in State v Pinnow. It appears on page 07/10.
" The testimony of Pinnow regarding the plastic case with foam interior expressly fitting his handgun matches the language of Section 167.31(1)(b) of the Wisconsin Statutes for an encased firearm. Compliance with Section 167.31 (1) and (2) of the Wisconsin Statutes always constitutes encasement and therefore concealment".
This statement could be important in an argument against the GFSZ statute. Essentially, in concert with the statement, compliance with 948.605 forces one to violate the concealed weapon statute 941.23. The WSC in Hamdan stated that 941.23 is a strict liability statute and without exception only a peace officer may go armed with a concealed and dangerous weapon(para 48). The WSC also ruled that concealement applies to unloaded as well as loaded firearms. 948.605 creates an exception that is not expressly allowed by 941.23. Also if judge watts statement withstands judicial muster then by the same token 167.31(2)(b) also creates an exception not within the strict liability declaration made by the WSC in Hamdan.
This ruling is much more significant than the unpublished ruling made in Alloy. Judge Watts ruling is a published ruling and published circuit court rulings may be cited as authority in any court. The importance of the ruling to our objectives is important. It is the first time a Wisconsin court has ruled that the encasement of a firearm always constitutes a concealed weapon. (emphasis on "always").
IANAL-- These are my opinions
