Lawyers have a legally recognized and defined duty to a specific individual client, who they advise, but who then instructs them.Imagine hiring a lawyer to represent you in court only they start pursuing issues counter to your own and your only recourse is to hire different lawyer, but only after paying them for 4 years.
MPs represent a constituency but at no point are elected with the expectation that they must and will adhere to a single inflexible viewpoint. With over a hundred thousand constituents per riding that’s unworkable. We choose MPs because we trust them as an individual to do the best they can for our riding in the aggregate.
I’d be ok with a high-threshold recall petition mechanism, but not automatic byelections.
