Not sure about with laws, but similar things have been tried with regulations. See http://redtapereduction.com/BC_Reg_Reform_Model.aspx http://redtapereduction.com/BC_Reg_Reform_Model.aspx but in brief: * Around 2001, voters in British Columbia elected a government with a specific campaign promise to reduce "regulation" by 1/3. * Initially this was accomplished by among other things setting a rule that for every new regulation introduced two existing ones had to be eliminated. * Then the status quo was maintained by mandating a 1-for-1 rule (each new regulation requires elimination of a existing one). * In 2015, the government of Canada introduced its own 1-for-1 rule. There are obviously complications around what constitutes "one regulation", which neither my summary nor the linked article completely capture.
