Another suggestion wastoreplace in paragraph (I)thewords"subject totheprovisions ofparagraph (3)ofthis article" bythewords"andthedecision reached pursuant tothatprocedure shallbe final". Thethrustofthesuggestion wastoallowthecourtcontrol envisaged in paragraph (3)onlyiftheparties hadnotagreed on aprocedure forchallenges and, inparticular, notentrusted aninstitution orthirdpersonwithdeciding onthe -25-challenge.
