If you receive a potential juror notice by the your local county, simply ignore it if it does not come certififed mail. There is no proof you received it and you can claim ignorance. They will reshuffle you and you will be notified again about a new date and simply ignore it again until it arrives certified receipt. You know the green form you have to sign for. Now if if the Federal Government sends you a notice that you will be a prospective juror in FEDERAL COURT. YOU MUST SHOW UP or you will have U.S. Marshalls searching high and low for you. You fail to show up for this then I advise you to bring your checkbook and toothbrush. Depending on the Judge you might be spending the night in the can. They will find you and they dont fuck around. That goes for being on any Federal Grand Jury, also. Additionally, the Federal Judge asks the questions during Voir Dire so you might want to rethink any bullshit excuse you might have. Federal Courts dont play. Your local state court will cut you more slack.
