Under what circumstances am I obliged to show ID to a police officer? In the UK, if a police constable stops you on the street and asks for your ID, when are you required by law to give it to them? Must there be reasonable suspicion of a crime? What about if you're driving and get pulled over; are you obliged to show your driving licence and/or ID? Does it make a difference whether it's a random stop or if you were speeding, e.g.?
People in the UK (who are not subject to immigration control or other restrictions) do not have to carry any form of identification. This doesn't answer all parts of your question, but s164 Road Traffic Act 1988 is appropriate to the part about driving. a person driving a motor vehicle on a road ... must, on being so required by a constable or vehicle examiner, produce his licence and its counterpart1 for examination, so as to enable the constable or vehicle examiner to ascertain the name and address of the holder of the licence, the date of issue, and the authority by which they were issued. (s164(1)) So it makes no difference why you were stopped: a constable or traffic offiver can demand production of your licence if you were driving. The same power exists if you're suspected of having caused an accident or committed an offence, even if you're not driving at the time of the production demand. Non-production is an offence: If a person required under the preceding provisions of this section to produce a licence and its counterpart ... fails to do so he is, subject to subsections (7) to (8A) below, guilty of an offence. (s164(6)) However, it is a defence to produce the licence (or a receipt for a licence) within seven days of the demand (s164(7-8)). In practice, the officer will give you a 'producer' requiring you to present your licence at a police station within seven days, after which you will be guilty of the non-production offence. The implication of this is that it is not required that you carry your licence; merely that you have it available to produce within seven days. 1 Presumably the reference to 'counterpart' will go away when the counterpart is abolished on 8th June 2015.
No Besides this being clearly unworkable, the requirements for the state providing public defense attorneys include being in need (you will need to provide an affadavit or similar to the effect) and when the defendant is at risk of significant time of confinement. The 5 to 15 minutes of the traffic or Terry stop are not considered significant. Nor are the processing times of arresting you and taking you in. Trying to make the officer provide you with an attorney (or declaring you aren't doing anything without one) before complying with their orders may well result in your incarceration and subsequent assignment of a public defender.
There are two questions here: Is it really the police, or someone pretending to be the police in order to stage a home invasion? If it is the police they will be wearing uniforms and showing you their badges. I don't know how common it is for criminals to impersonate police officers. Do they have a valid search warrant? Once you have established that they really are police your best course is to stand back and let them in. Arguing about search warrants and &quot;fruit of the poisoned tree&quot; is a job for a lawyer later on. One option might be to quickly dial 911, put the phone down but still listening, and then open the door while saying &quot;are you police, can I see your badge?&quot;. If they are police then no problem. If they turn out to be imposters then the 911 dispatcher should be able to figure it out and send the real police around.
Does the party have any legal leverage to engage the police (or other competent authorities apart from private investigators) to help locate the witness and serve the summons on them? Not really. Legal process is not infrequently served by a sheriff's deputy. But the deputy will not generally take any initiative to locate a person to be served beyond what it provided by the litigant. The main reasons to have a sheriff's deputy serve someone with process is the fear that the person served might react violently. Or is it just the party's bad luck that the witness cannot be located and served on? Pretty much.
Regarding being pulled over, the guidance at Learn to drive a car: step by step states (emphasis mine): If a police officer asks you to, you must be able to show: your driving licence a valid insurance certificate a valid MOT certificate (if your vehicle needs one) If you don’t have the documents with you at the time, you may be asked to take them to a police station within 7 days.
Name and date of birth are not sufficiently unique to identify a person. While name, date of birth, and place of birth do not have to be unique, either, it reduces the number of false positives. Also, date of birth is somewhat better known than place of birth for most people. Motorist: &quot;Sorry, officer, I seem to have lost my wallet. Everything was in there, ID, license, ...&quot; Cop: &quot;Tell me your name, date and place of birth, and I'll run a query if you do have a license.&quot;
I'm not a lawyer; I'm not your lawyer. Victoria The Road Safety Act 1986 (Vic) s 73A makes the obstruction of the operation of a safety camera or speed detector an offence. It is likely that the obstruction of a mobile speed camera would fall within this offence. The law does not restrict the operation of the device to police, and so it may not be relevant whether the car was marked or not. New South Wales Certainly, the obstruction of an authorised officer is an offense as per the Roads Act 1993 (NSW) s 240 and the Road Transport Act 2013 (NSW) s 173 Obviously these apply to NSW and Victoria only; I haven't researched the other states yet. It's possible, though not definite, that other states will have similar laws. It is also likely, though not definite, that people who attempt to obstruct it may be charged with obstruction of traffic in some way, as most states require you to not obstruct the normal passage of traffic unreasonably. (eg Road Obstruction (Special Provisions) Act 1979 (NSW) s 4)
Since there is no search or seizure involved in having a driver's license, requiring a person to update their address is not a violation of the 4th Amendment. It is also not "testifying against oneself in a criminal case", so it does not violate the 5th. As has been repeated many times, driving is a privilege and not a right, meaning that there is no fundamental constitutional right to drive. Strict scrutiny would not render the requirement to have a license unconstitutional, and it certainly would not invalidate the requirement to give a correct address and update that address as necessary. There may be issues regarding a requirement to produce identification, but there is no legal precedent for the idea that an ID law law and a federal "must show" statute would violate the 4th (that is not to say that the courts could not find there is such a basis if the question arises, but it has not yet been found). Since there is no national ID law, one can only conjecture what the outcome of judicial review would be, but if such a law survived strict scrutiny, it would be inconceivable that a portion of the law requiring you to keep your address current would fail such scrutiny. A curiosity search would still be barred.
