How they reason — coded from their reports

Coles' caseload combines Permission in Principle applications and statutory Certificate of Lawful Development cases, and she is distinctive for explaining the two-stage Permission in Principle process itself (principle stage then technical-details stage) before applying it, rather than assuming familiarity, and for reciting the exact statutory text of Sections 191/171B of the Town and Country Planning Act 1990 verbatim in Certificate of Lawfulness assessments before applying it to the facts. On major residential schemes she engages directly with evolving London Plan density/optimisation policy (citing both the adopted and then-emerging Draft London Plan Policy D3), tracking policy transitions explicitly rather than citing only the final adopted version.

Observable habits

· explains the two-stage Permission in Principle process (principle stage, then technical-details consent stage) explicitly before applying it to a specific application

· recites the exact statutory text of Sections 191/171B of the Town and Country Planning Act 1990 verbatim before applying it to the facts of a Certificate of Lawfulness case

· tracks London Plan density/optimisation policy through its transitional (adopted vs. then-emerging Draft) states explicitly, rather than citing only the final adopted policy

What their reports consistently look for

· whether an application properly falls within the Permission in Principle route's limited scope (location, land use type, amount of development only)

· verbatim statutory compliance with Sections 191(2)/171B TCPA 1990's lawfulness/time-limit tests

· whether a major scheme's density and unit mix align with London Plan Policy D3/Table 3.2 density-range guidance, tracked across policy versions

In their own words

the first stage (or permission in principle stage) establishes whether a site is suitable in-principle and the second (`technical details consent') stage is when the detailed development proposals are assessed

S.191 (2) states that "For the purposes of this Act uses and operations are lawful at any time if-- (a) no enforcement action may then be taken in respect of them
