Is Someone Else's Purpose An Improper Purpose?

This post on the Harvard Law School Forum on Corporate Governance and Financial Regulation discusses Vice Chancellor J. Travis Laster's recent decision in Wilkinson v. A. Schulman, Inc., 2017 Del. Ch. LEXIS 798.  The case involved a stockholder's demand for inspection under Section 220 of the Delaware General Corporation Law.  Vice Chancellor Laster denied inspection based on the stockholder's failure to demonstrate a proper purpose as required by Section 220:

On the record presented in this case, the Company proved that Wilkinson's purported purposes were not his actual purposes. They were his counsel's purposes.

How would this case fare under Nevada's corporate law?  Nevada's inspection statute, NRS 78.257, differs in many ways.  Under the Nevada statute, a corporation may deny inspection if the stockholder refuses to furnish the corporation with "an affidavit that such inspection, copies or audit is not desired for any purpose not related to his or her interest in the corporation as a stockholder".  In other words, the stockholder may be required to disavow any improper purpose, even though the stockholder may have one or more proper purposes.  The question then becomes whether someone else's purpose is a purpose not related to a stockholder's interest in the corporation qua stockholder.
