Rules in Wisconsin
When a bill is introduced or an order is issued, it is drafted from the legislature's or the commission's own text and published here after a person reads it. Local rules, county and city ordinances and moratoriums, stay on the Wisconsin scorecard.
A law here is one statute, utility commission order, tariff, tax rule, moratorium or bill at the state level. What it requires is taken from the text, never summarized from coverage; a date the text does not give is left empty. Its status is one of five, defined on the laws index. The dated events beneath a law are the scorecard entries that cite it.
