Isnt the thing with the car door opening that its ok to open a car door with the due care but its not ok to open the car door without due care and thereby cause injury to another person as a result.
Presumably a lawyer could assert that the act and resulting injury is in itself enough evidence to establish lack of due care.
Exactly, it also has to be proven beyond reasonable doubt. That's an extremely high burden of proof.
I think the problem with your earlier statement was that you mentioned the cyclist was in the door zone and used the term "by the same token" - suggesting equal responsibility.
I appreciate you have clarified the details of the collision, but to be honest, if every driver said they had opened the door 6 inches would that be sufficient for you not to proceed? There is not a min limit is there?
To answer your question, I'd be interested in the nature and extent of the cyclist's injuries, damage to the bike and door to glean if the 6 inch story could be in any way corroborated. What's more, it's much easier to avoid a door that has been opened 6 inches, rather than 3 foot for example. Did the driver say he checked before opening the door?
Anyway, this is OT and I am not having a go.
Yes poor wording on my part, the cyclist did contribute to the accident by being in the door zone but clearly that isn't the cause. They cyclist broke a bone in her knee, no damage to the bike or the car, no corroboration at all, one word against another.
Incidentally one word against another is 50/50, that's a not guilty verdict straight away.
In addition the highway code says you should "Leave plenty of room when passing parked vehicles and watch out for doors being opened or pedestrians stepping into your path" when cycling. No defence solicitor in the world would not bring this up in court. The driver was adamant they checked and nothing was there, they then opened the door only 6 inches before the cyclist hit.
Not easy to make a decision is it? Proceed and you are potentially wasting thousands of pounds of taxpayers money, don't proceed and the car driver potentially gets away with an illegal act.
I might add that I was swinging in favour of prosecution but once I'd discussed it with supervision the lack of any independent witnesses killed it.
Except that's not your decision to make - it is the decision of the CPS. It is your duty as a police officer to investigate fully and, where there is evidence of an offence (in this case there clearly was as it is an absolute offence), submit a file to the CPS. It is for the CPS to apply the public interest and realistic prospect tests.
Not in the case of low level traffic offences it isn't, nor low level criminal offences either. The offence is absolute, the test would be was the door opened so as to cause a danger?
Do you really think it's a valuable use of public funds for me to spend 4 hours minimum putting a prosecution file together to send to CPS who spend another half an hour looking at it for something that would result in a fine of £30. It would cost more than that in paper, hence the public interest test. If it was an open and shut case then yes, this wasn't and would have likely gone to trial resulting in a bill of at least a few thousand quid to the tax payer that had little chance of resulting in conviction.
