So was the cal cert OK? So I'm wasting my time with this

What would you have done if the calibration certificate had expired?

Even if it wasn't, you'd need to prove it was wrong. So yes you're wasting your time trying to find a loophole.

The certificate doesn't really matter.

There is a legal presumption that the camera is working properly - unless you can prove otherwise.

How would you do that?

And even if you tried to prove it, the prosecution will roll in a very expensive (for you) expert witness to show you are wrong.

Yes, that's why I was trying to get an answer.

The device is assumed to be reliable unless doubt can be cast on its accuracy. An expired calibration certificate does not mean it cannot be relied upon. It does not suddenly become unreliable the day after the certificate expires. 

Whilst it may support any evidence there might be to cause a court to doubt its accuracy, by itself it is very unlikely to succeed.

I don't really know why police make calibration certificates available as a matter of routine, before prosecutions. I suppose they think it might forestall any frivolous defences.
