First of all, why was he sent to 'Hatch Street' and for what purpose?
reading between the lines, I'm guessing hubby is on casual/short-time working? That would be why he has to have employer certify his working days on a weekly basis. Due to backlogs, I'd imagine that he ran out of weeekly slips before his claim was authorised? And so claim auto-closed when not updated? It should only be a matter of back-dating it when repalcements/new siging slips are furnished to SW. (there's a lot of reading between the lines there!)
