Levi Woodbury,
Mason v. Fearson — Opinion of the Court
“ The power is conferred for their benefit, not his; and the intent of the legislature, which is the test in these cases, seems under such circumstances to have been 'to impose a positive and absolute duty.' But, under other circumstances, where the act to be done affects no third persons, and is not clearly beneficial to them or the public, the words 'may' do an act, or it is 'lawful' to do it, do not mean 'must,' but rather indicate an intent in the legislature to confer a discretionary power. ”
