How they reason — coded from their reports

Brocklesby's Certificate-of-Lawfulness refusals itemise the exact gap length in months/years for each individual flat's tenancy evidence, rather than a general 'insufficient evidence' statement, and she is explicit that missing evidence for even one unit (of several) undermines the whole certificate.

Observable habits

· itemises the exact length of each specific tenancy-evidence gap, unit by unit, rather than a general insufficiency statement

· treats missing evidence for even ONE unit among several as undermining the whole certificate application, not just that unit

· cross-checks Council Tax band records against the applicant's claimed unit count to spot inconsistencies

What their reports consistently look for

· what this officer's reports consistently look for: the exact length of each individual unit's tenancy-evidence gap, itemised rather than summarised

· what this officer's reports consistently look for: whether EVERY unit in a multi-unit certificate has continuous evidence — one missing unit is treated as fatal to the whole application

· what this officer's reports consistently look for: whether Council Tax band records match the applicant's claimed number of self-contained units

In their own words

it is clear that Flat A has been rented from 2018 until 2024, however there is a four month gap in tenancy agreements from 01/01/2021 to 20/05/2021. In addition, there is a two year gap from 01/06/2018 to 23/11/2020 for Flat B, an eight month gap from 18/08/2018 to 01/04/2019 for Flat D

2023/1825

It is noted that there is no evidence for flat C. No piece of evidence has shown that any flat has been in continuous use as self-contained residential dwelling for a period of four years or more prior to the date of this application.

2023/1825

The Council Tax band register has the property listed as two flats, not six, as follows: Flat Second Floor; 174 Clarence Road; and 174 Clarence Road
