Here is a link to a good discussion by Priya Cherian Huskins, Esq. at Woodruff-Sawyer about director note taking (not minute taking, but note taking), which can also apply to note taking in general in many situations, CLICK HERE. I agree with Ms. Huskins.
There should be policies and procedures or guidelines to be followed, but a director should be allowed to take notes, and should not be told that he or she cannot take notes. It is a matter of the director performing his or her oversight function in the manner that he or she believes is prudent and necessary. If I was told that as a director or audit committee member that I could not take notes that I thought were necessary and helpful to me and my oversight, I would question that instruction or request, and consider declining the position if it was forced.
