9 allowed and 20 dismissed (29 decided), plus 2 split decisions. That is 4.5 percentage points below the national average of 35.5%. Across all years: 30.2% of 338 decided.

Small sample: with this few decisions the percentage can swing a lot from one year to the next.

Allowed ÷ (allowed + dismissed). Split decisions, withdrawn, invalid and undetermined appeals are left out. Based on completed records in the Appeal Scout archive, which runs a little behind today's date because decisions are added after publication.
