The article discusses three ethical obligations which bear on attorney-client confidentiality in America in cases involving client perjury as of 2015, and it mentions how U.S. lawyers are required to learn as much as they can about their clients' cases, inform their clients of a lawyer's obligation to keep information confidential, and reveal confidential information to a court if an attorney knows that a client has committed perjury. The American Bar Association's ethical rules are examined.
