All asylum claims lodged in the UK are carefully considered on their individual merits against a background of relevant case law and up to date country information. We ensure that claimants are given every opportunity to disclose information relevant to their claim before a decision is taken, even where that information may be sensitive or difficult to disclose.
We are working to improve the quality of decision-making to ensure that we properly consider all the evidence provided and get decisions right the first time. UK Visas and Immigration has an internal audit process, consisting of reviews by senior case workers and independent auditors, which assesses whether Home Office policy has been followed.
An allowed appeal is not in itself an indication that our decision was incorrect at the time it was made though we aim to reduce the allowed appeal rate by analysing the reasons why appeals are allowed and using this to further improve guidance and training.
