An Illinois Assistant Attorney General is the subject of an interesting ethical charge after allegedly using a "ruse” to gain evidence against a condominium project for lack of handicapped access. He is accused of entering the premises under the false pretense that he was looking for a condo for his grandmother. More on the story here. The complaint is available here.
This is an example of an old question: whether it is ethical to engage in some level of deception in order to confirm whether someone else is discriminating.
Assuming all the facts are true, the lawyer in question was, in fact, dishonest. But he was dishonest "with good intentions" or for a good reason -- in order to find whether the other party was violating the law.
In part, the solution to the problem might be simply to let others do the investigating or, as in this case, the "testing." Attorneys should stay out of it and wait until the information is gathered to intervene in the prosecution. On the other hand, an attorney can't ask someone to do something the attorney can't do himself, so I am not sure where that leaves the attorney who needs to engage in some level of deception to gather the information.
