Editing John Doe (section)

==In criminal investigation==
In other [[English-speaking countries]], unique placeholder names, numbers or [[codename]]s have become more often used in the context of police investigations. This has included the [[United Kingdom]], where usage of "John Doe" originated during the [[Middle Ages]]. However, the legal term ''John Doe injunction'' or ''John Doe order''<ref name="order">{{cite web |url=http://www.pressgazette.co.uk/story.asp?storyCode=30920&sectioncode=1 |title=Obtaining a John Doe order |publisher=PressGazette |access-date=2 October 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120911032452/http://www.pressgazette.co.uk/story.asp?storyCode=30920&sectioncode=1 |archive-date=11 September 2012}}</ref> has survived in [[English law]] and other legal systems influenced by it. Other names, such as "[[Joe Bloggs]]" or "John Smith", have sometimes been informally used as placeholders for an every-man in the UK, Australia, and New Zealand; however such names are seldom used in legal or police circles in the same sense as John Doe.

Well-known legal cases named after placeholders include:
* The landmark 1973 [[Supreme Court of the United States|US Supreme Court]] decisions regarding abortion: ''[[Roe v. Wade]]'' ("Roe" being a pseudonym) and ''[[Doe v. Bolton]]'' (1973); and
* The civil cases ''Doe dem. John Hurrell Luscombe v Yates, Hawker, and Mudge'' (1822) 5 B. & Ald. 544 (England),<ref name="england">{{cite web|url=https://deedpolloffice.com/change-name/law/case-law/Doe-dem-Luscombe-v-Yates-1822|title=Deed Poll Office (D·P·O)|website=Deed Poll Office|access-date=4 December 2018|archive-date=22 March 2019|archive-url=https://web.archive.org/web/20190322134926/https://deedpolloffice.com/change-name/law/case-law/Doe-dem-Luscombe-v-Yates-1822|url-status=live}}</ref> ''McKeogh v.
