Yes and as I said, CodeIgniter gives you that freedom. This forum is for best practices and that's what the OP asked. What you consider a best practice may differ.

You're absolutely right about that, the could should be:
PHP Code:
if($this->validateData($data, 'newsletter'))
$validatedData = $this->validator->getValidated();
The controller does instantiate it automatically, but only after you use one of the validation methods.
