<P> The definition of "public place" is unsettled, but can loosely be defined as anywhere the public have a legitimate right to be whether this access is paid for or not, which could include any populated area within the England and Wales, including one's motor vehicle, which is defined by law as a' public place' unless parked on private property . In a remote or otherwise unpopulated area, a public place could include: 1) an organised wilderness gathering or event; 2) a National Park; 3) Forestry Commission land that is held open to the public; 4) public footpaths; 5) bridleways; and 6) any area where an individual does not need to ask specific permission to walk, camp, or travel from a landowner . </P> <P> The phrase "good reason or lawful authority" in Subsection 4 is intended to allow for "common sense" possession of knives, so that it is legal to carry a knife if there is a bona fide reason to do so . Subsection 5 gives some specific examples of bona fide reasons: a knife for use at work (e.g. a chef's knife), as part of a national costume (e.g. a sgian dubh for Scottish Highland dress), or for religious reasons (e.g. a Sikh Kirpan). However, even these specific statutory exceptions have proven unavailing to knife owners at times . It is important to note that "good reason or lawful authority" exceptions may be difficult to establish for those not using a knife in the course of their trade or profession, but merely because the knife is needed in case of emergency or for occasional utility use . </P> <P> Although English law insists that it is the responsibility of the prosecution to provide evidence proving a crime has been committed, an individual must provide evidence to prove that they had a "good reason or lawful authority" for carrying a knife (if this is the case) upon being detained . While this may appear to be a reversal of the usual burden of proof, technically the prosecution has already proven the case (prima facie) by establishing that a knife was being carried in a public place (see Violent Crime Reduction Act 2006 on Knives, etc.; New powers to tackle gun and knife crime) </P> <P> As the burden of proving "good reason or lawful authority" lies with the defendant, it is likely that an individual detained and searched by the police will need to prove the following (sometimes known as the THIS list): Has THIS person got permission; to use THIS article (knife); for THIS use; on THIS land; and by THIS land owner . </P>
