My offence fell into the 'Automatic Barring with right to representations" category and I received a DBS letter giving me 8 weeks to make written representations.
I composed an objective and structured letter outlining reasons why the barring would be disproportionate and inappropriate. Wherever possible, I quoted from my pre-sentence reports (especially the Risk sections) and also included some relevant quotes from character witness statements used during my trial.
I spoke to the DBS this week to check status (3 months has elapsed). They told me that they are in the process of collecting further evidence and are waiting to receive a copy of the judge's sentencing remarks.
I don't know what the eventual outcome will be and will post to the forum when I hear. The positive is that they are taking action to get more information and didn't reject out of hand. The unknown is whether that is done as a matter of course and therefore no one with any decision making power has actually reviewed my representations in detail.
