The issue became a burning one when a Muslim juror came to court wearing a burkah, covered from head to toe in a black robe. The juror’s entire head and face were covered except for a slit in the area of her eyes.

The lawyers contended, “The mere fact that a potential juror wears a burkah or hijab is not a basis of itself to be excluded from sitting.”

The reference to the hijab is a red herring, for a hijab does not cover the face. (See graphic at right.)

“Based on the prevailing law, the mere fact that a juror is of a particular race, or has a particular religious belief cannot be a challenge for cause by the prosecution or the defence,” the lawyers argued.

Neither race nor religion is relevant here.  Islam is not a race, and Islam does not require all Muslim women to wear a burqa.

The question the judge should be pondering is: Are people wearing masks allowed to serve as jurors?
