Maryland Rules of Civil Procedure|Rule 2-512 - Jury Selection

                                                
(a) Jury Size and Challenge to the Array.
(1)Size. Before a trial begins, the judge shall decide (A) the required number of sworn jurors, including any alternates, and (B) the size of the array of qualified jurors needed. 
Cross reference: See Code, Courts Article, § 8-421(b).
(2)Insufficient Array. If the array is insufficient for jury selection, the trial judge may direct that additional qualified jurors be summoned at random from the qualified juror pool as provided by statute.
(3)Challenge to the Array. A party may challenge the array on the ground that its members were not selected or summoned according to law, or on any other ground that would disqualify the array as a whole. A challenge to the array shall be made and determined before any individual member of the array is examined, except that the trial judge for good cause may permit the challenge to be made after the jury is sworn but before any evidence is received.
(b) General Requirements. All individuals to be impanelled on the jury, including any alternates, shall be selected in the same manner, have the same qualifications, and be subject to the same examination.
(c) Jury List.
(1)Contents. Before the examination of qualified jurors, each party shall be provided with a list that includes each juror's name, address, age, sex, education, occupation, spouse's occupation, and any other information required by Rule. Unless the trial judge orders otherwise, the address shall be limited to the city or town and zip code and shall not include the street address or box number.
(2)Dissemination. 
(A) Allowed. A party may provide the jury list to any person employed by the party to assist in jury selection. With permission of the trial judge, the list may be disseminated to other individuals such as the courtroom clerk or court reporter for use in carrying out official duties.
(B) Prohibited. Unless the trial judge orders otherwise, a party and any other person to whom the jury list is provided in accordance with subsection (c)(2)(A) of this Rule may not disseminate the list or the information contained on the list to any other person.
(3)Not Part of the Case Record; Exception. Unless the court orders otherwise, copies of jury lists shall be returned to the jury commissioner. Unless marked for identification and offered in evidence pursuant to Rule 2-516, a jury list is not part of the case record. 
Cross reference: See Rule 16-934 concerning petitions to permit or deny inspection of a case record.
(d) Examination and Challenges for Cause.
(1)Examination. The trial judge may permit the parties to conduct an examination of qualified jurors or may conduct the examination after considering questions proposed by the parties. If the judge conducts the examination, the judge may permit the parties to supplement the examination by further inquiry or may submit to the jurors additional questions proposed by the parties. The jurors' responses to any examination shall be under oath. On request of any party, the judge shall direct the clerk to call the roll of the array and to request each qualified juror to stand and be identified when called.
(2)Challenge for Cause. A party may challenge an individual qualified juror for cause. A challenge for cause shall be made and determined before the jury is sworn, or thereafter for good cause shown.
(e) Peremptory Challenges.
(1)Designation of Qualified Jurors; Order of Selection. Before the exercise of peremptory challenges, the trial judge shall designate those individuals on the jury list who remain qualified after examination. The number designated shall be sufficient to provide the required number of sworn jurors, including any alternates, after allowing for the exercise of peremptory challenges. The trial judge shall at the same time prescribe the order to be followed in selecting individuals from the list.
(2)Number; Exercise of Peremptory Challenges. Each party is permitted four peremptory challenges plus one peremptory challenge for each group of three or less alternates to be impanelled. For purposes of this section, all plaintiffs shall be considered as a single party and all defendants shall be considered as a single party unless the trial judge determines that adverse or hostile interests between plaintiffs or between defendants justify allowing one or more of them the separate peremptory challenges available to a single party. The parties shall simultaneously exercise their peremptory challenges by striking names from a copy of the jury list.
(f) Impanelled Jury.
(1)Impanelling. The individuals to be impanelled as sworn jurors, including any alternates, shall be called from the qualified jurors remaining on the jury list in the order previously designated by the trial judge and shall be sworn.
(2)Oath; Functions, Powers, Facilities, and Privileges. All sworn jurors, including any alternates, shall take the same oath and, until discharged from jury service, have the same functions, powers, facilities, and privileges.
(3)Discharge of Jury Member. At any time before the jury retires to consider its verdict, the trial judge may replace any jury member whom the trial judge finds to be unable or disqualified to perform jury service with an alternate in the order of selection set under subsection (e)(1). When the jury retires to consider its verdict, the trial judge shall discharge any remaining alternates who did not replace another jury member.
(g) Foreperson. The trial judge shall designate a sworn juror as foreperson.
