The city council is considering a new ordinance to require stores to provide reusable bags and eliminate disposal paper or plastic bags. In determining whether to pass the law, the city council obtained an estimate for the expense stores would incur in offering reusable instead of disposable bags. They also obtained an estimate for the savings which would result from not having to clean up litter from disposable bags. Finally, they consulted with an environmentalist to assess the positive impact that phasing out bags would have, including enhanced safety for local wildlife. In deciding whether to pass the law, the council relied on:_________
a.The historical school
b. Stare decisis
c. A cost benefit analysis
d. Common law
e. Legal positive
