Review of compensation for those wrongfully imprisoned

At the moment there are two different limits to the compensation that can be awarded depending on whether the applicant spent less than or more than 10 years in prison. I believe these timeframes are too broad. I think the current compensation levels are not reflective of time lost, making it difficult for someone to get their life back on track who has been wrongfully imprisoned for a long period. I also want the review to consider taxation to ensure these payments are clearly tax exempt as I believe it is only fair that compensation is not taxed.
