1.  Determination.  Upon request of a prospective juror, the presiding justice or the clerk of court acting under the supervision of the presiding justice shall determine whether the prospective juror is excused from jury service. The determination must be made on the basis of information provided on the juror qualification form, supplemented by other competent evidence when considered necessary to the determination.  

2.  Basis for excuse.  A qualified prospective juror may be excused from jury service only upon a showing of undue hardship, extreme inconvenience, public necessity or inability to render satisfactory jury service because of physical or mental disability.  

3.  Extent of excuse; record.  Depending upon the circumstances, a juror may be finally excused from jury service, be required to serve at a later specific time or be required to serve for a period of time less than the usual 15 court days. The clerk shall enter the determination regarding the requested excuse and the reason for the determination in the appropriate record kept for that purpose.
