After reading and re-reading the original document that refers to a Fisc ( Charter in which King John Confirms the grant of land to the men of Laxfield ) note the word confirms, this is a confirmation of a grant that was given by the Duke Henry of Louvain to the men of Laxfield and it should be noted that King John was at this time trying to keep favour and was reconfirming grants all over England. The Duke refered to in the grant may have been some years earlier and that they(the decendents of the "men of Laxfield") wished to make certain that the lands and rights were confirmed and understood by the then ruling King. I have and am still searching and researching records that may lead me to reference to or hopefully the original grant.
