A legal challenge to a new $63-million Minnesota Senate Office building has been dismissed. The judge in the case on Thursday ruled against a former Republican legislator who wants to block construction of the new building. The judge said former state Representative Jim Knoblach’s claim that authorization of the building was flawed didn’t hold up and that the building was legitimately included in a larger tax bill that lawmakers passed last year. The project, which includes a separate $27-million parking ramp, still needs one more legislative sign-off. Members of the House rules committee must OK the building design. Democratic House Speaker Paul Thissen says that other less-expensive options should be considered.
