Speeding ticket question

[Max Preload]

It was never mentioned as they are instant fines, and I was there for speeding only. However, If I had been involved in an accident....I would've been screwed.
I was there purely to defend myself in the speeding charge, nothing else.

There's no such thing as an 'instant fine'. What you're referring to is an infringement offence notice which when the fee for the infringement is paid becomes an admission of guilt of the infringement.

You can challenge any ION in court.

You are right, I just called them instant as they were way out at the time.
Guilty as charged.
There are alot of procedures police have to follow to the letter, and if they don't follow each step exactly, A lawyer will eat them alive in court.

stare decisis means judges don't just look at previous cases, but are actually bound by them. that is a given.

Ratio decidendi is 'the reason for deciding'.
One presents their similar case in a light closely resembling the precident, working towards a known outcome of course.

Justice of the Peace's are appointed by the Governor-General, their appointment is for life, and have not had any legal office. They receive a rudimentary correspondence course in the NZ legal system and a manual.
They are not paid.

Their decisions go no where if you are lucky to get off.

However, everyone with a similar case would expect to be treated equally under the law and, technically, there is only one court, but various locations.
