Don't know if this helps but the definition of nearest point of relief supports your chairman and says (see the Note) :

"The "nearest point of relief" is the reference point for taking relief without penalty from interference by an immovable obstruction (Rule 24-2), an abnormal ground condition (Rule 25-1) or a wrong putting green (Rule 25-3).

It is the point on the course nearest to where the ball lies:

(i) that is not nearer the hole, and

(ii) where, if the ball were so positioned, no interference by the condition from which relief is sought would exist for the stroke the player would have made from the original position if the condition were not there.

Note: In order to determine the nearest point of relief accurately, the player should use the club with which he would have made his next stroke if the condition were not there to simulate the address position, direction of play and swing for such a stroke."

However I'm sure I've see pros use their drivers or long handled putters under these circumstances so they may be a ruling somewhere else.
