Recent evidence suggests that Sid is not alone now that RLE claims are authorised centrally and there is no scope for discretion to be used by unit allowances staffs.
Another example that some people have fallen foul of is that you must (according to the JSP) be posted at least 50 miles away from your home in order to claim legal fees on sale/purchase of a property. JPAC(Centurion) are using the National Breakdown website to check mileages and have reputedly rejected a claim for someone who was posted 49.8 miles away from his home.
The only thing to do is to jump through the hoops of staffing casework through your Unit HR to JPAC PACC, which I feel sure will be supported. If enough similar cases are presented they will have the grounds to recommend a policy change.
