In many cases justice doesn't necessarily relate to legal at all. For instance, in New York City a crook filed to transfer the deeds to some houses. When the owners found out their only recourse was to hire a lawyer and go to court. The office where deeds are filed admitted they had a problem.
Should the proper owners of the properties have to shoulder the cost of a bad government action? Should our justice department consider the issue of justice in this case and step in and represent the real property owners?
In another case a lawyer was suing store owners about complying with ADA (like for wheelchair access) simply to make money from thestore owners, not to help any disabled people. Furthermore, the historical preservation laws prohibited the changing the store front for ramps. The burden of hiring a lawyer out some of the store out of business. Should the Justice Department prevent this injustice?
Without lots of money many people cannot be protected from many things not necessary in their control otherwise. Should the government make sure everyone receives justice? Should the Justice Department insure all people have equal rights to justice, even without a legal issue?
