Our constitution

The rules we are governed by

Our constitution is the rule book we are governed by.  Changes to the constitution can only be made with the approval of HIS members, and the Charity Commission must be informed of any changes made.  When HIS was formed in 1980, its purposes and the rules for how it should operate are were set down in a governing document. Over time, as HIS has evolved, a number of changes have been made.  Most recently (2021) changes were approved in order to ensure the recruitment of new Trustees involves an open call to members, and final selection by HIS Council based on skills gaps identified.
