Legal Principles

Principles governing costs orders.

HHJ Monty KC's judgment (paras 19-24)

Standard for granting permission to appeal.

Implicit in the judge's decision-making process.

Outcomes

Permission to appeal refused.

Mr. Khodaparast failed to identify any arguable ground of appeal; the judge's decision was not demonstrably 'wrong'. The appeal court's role is not to re-hear arguments, but to assess whether the lower court applied the wrong test, made an impermissible factual finding, or reached an otherwise flawed evaluative judgment.
