Oh, wait....

The effort to sweep aside the 23-year-old Michigan vs Jackson ruling is one of several moves by the new government to have dismayed civil rights groups.

President Barack Obama has already provoked controversy by backing the continued imprisonment without trial of enemy combatants in Afghanistan and by limiting the rights of prisoners to challenge evidence used to convict them.

The Michigan vs Jackson ruling in 1986 established that, if a defendants have a lawyer or have asked for one to be present, police may not interview them until the lawyer is present.

Any such questioning cannot be used in court even if the suspect agrees to waive his right to a lawyer because he would have made that decision without legal counsel, said the Supreme Court.

However, in a current case that seeks to change the law, the US Justice Department argues that the existing rule is unnecessary and outdated.
