Can I ask for evidence on motoring offence

I doubt you'll receive anything tbh, he would have given it to you there and then.

If you have been wronged by the Garda you will have to plead your case in court.If your evidence is believable you will be acquited.

The Garda will just say that they saw you on the phone. To fight it you need to go to court and as @Luna84 said it'll be your word against the Garda, the judge will believe the Garda. The offence is holding not using so call/data logs are no use. Unless you have a driver facing camera you can't win.

When he is denying the charge in court he can make reference to the fact that he put in a complaint to the ombudsman and requested and/or wrote to the superintendent or inspector.

It might make the guard think twice the next time especially if there are multiple complaints coming in from the public about him.

You don't get the fine handed to you at the roadside.

I fought this and won. A jumped up garda in naas pulled me over for what i thought would have been dirty number plates, he then said i was on my phone, that he seen me on the phone, he refused to give me his name and i was in total shock so to cut a long story short , i had no credit that day as it was the day before payday(paid monthly) and i provided my call logs that i hadnt been on the phone nor sent or recieved any messages to my solicitor. The guard never turned up to court and it was thrown out in the day.

All in all i would have went to prison before i paid that wrongful fine, the guy was a complete d**ckhead and the fact is you cannot randomly stop someone for revenue for no reason

If it was a traffic core vehicle they are equipped with Dash Cams. Get a solicitor to go to the station and request the footage of the stop if you have received a fix notice for this.

How are your call logs evidence?

You would be trying to prove a negative.

How are you able to prove it wasn't you using a different phone or SIM? If the guard took all the details fine, you could be tied to that equipment at that time, but if he took those details he would know full well a prosecution was pointless.

Even with the phone details confirming no calls, if he didn't search yourself and the car for another device, then your evidence is a tad lacking.

If the Garda can't provide video footage and op's call logs show other calls that day but not at the time of the offence I'd expect it to be dismissed. This assumption the Judge will believe everything a Garda says is misguided, he'll need to prove an offence took place and said isn't good enough if there's contradictory hard evidence.

Op needs to find out what solicitors work that court and contact one of them if the notice does appear and he has some evidence.

Correct, having evidence you weren't using the phone for a call and having a car kit installed at the time of the offence is in his favour though. The Garda has no evidence it seems in this case. Then it's down to the Judge to weigh up the evidence and with op's clean record and a good solicitor the Garda may lose his case which believe it or not does happen.
