Caseworkers considering right of abode applications are experienced and suitably trained.
In February 2020, as part of the reinspection report into failed right of abode applications, the Independent Chief Inspector for Borders and Immigration (ICIBI) reviewed current training packs and materials used to train Right of Abode (RoA) caseworkers. The report can be found at https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/865201/ICIBI_Failed_RIght_of_Abode_Web_version.pdf
Paragraph 3.20 on page 7 of the report in particular states “According to the evidence provided for this reinspection, the numbers of RoA applications received each year are small, around 1,200; the trend is downwards; the refusal rate is low, 10 to 12% in the last two business years; guidance and SOPs are up-to-date; and, caseworkers are experienced and appear genuinely committed to providing good customer service.”
Caseworkers have discretion when dealing with Commonwealth Citizens who have resided for a long time in the UK. The caseworker guidance can be found on gov.uk: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/807365/windrush-scheme-casework-guidance-v3.0-ext.pdf
Page 11 of the caseworker guidance states “You should recognise that people may not have documents that are over 30 years old and help people to build a picture of their life in the UK, using documentation and evidence provided, or that you can access through systems available to you, including through use of cross-departmental data sharing.”
Furthermore, the guidance is clear on page 13 that caseworkers “must take a rounded view where evidence is not provided that proves matters of fact and decide the case on balance of probability, taking into account the picture of life in the UK, evidence in the round and criminality.”
