How they reason — coded from their reports

Bertwistle's flat-amalgamation cases cite the specific DM20/DM23 policy pairing and confirm no loss of three-or-more units occurs, and his lawfulness-certificate refusals point to a specific missing document type (Council Tax records for the specific unit) as the decisive gap.

Observable habits

· confirms explicitly that an amalgamation does not breach the 'loss of three or more dwellings' policy threshold before endorsing it

· names the exact missing document type (e.g. Council Tax records for the specific flat) as the decisive gap in a lawfulness case

· notes when an application's own supporting statement references unrelated addresses/wards, flagging this as a quality-of-evidence concern

What their reports consistently look for

· what this officer's reports consistently look for: explicit confirmation that a flat amalgamation does not cross the three-or-more-dwellings loss threshold

· what this officer's reports consistently look for: the specific named document type missing from a lawfulness case (e.g. Council Tax records for the specific unit)

· what this officer's reports consistently look for: whether an applicant's own supporting statement contains errors (wrong address/ward references) that undermine its reliability
