In common usage, the phrase 'flag burning' refers only to burning a flag as an act of protest. However the United States Flag Code states that "the flag, when it is in such condition that it is no longer a fitting emblem for display, should be destroyed in a dignified way, preferably by burning," ideally by an authorized organization with a suitable ceremony accompanying.
Elizabeth O'Shea, an Australian student, burned the Flag of Australia in 2002; she was not charged. In May 2002, several prominent politicians advocated the banning of flag burning, but were rejected by the Prime Minister.
During the 2005 Cronulla riots, a Lebanese-Australian youth, whose name has been kept secret, climbed an RSL club and tore down its flag before setting it on fire. The youth was sentenced to 12 months probation for the destruction of the RSL's property. In October of that year the youth accepted an invitation from the RSL to carry the Australian flag along with war veterans in the Anzac Day march the following year. However, the RSL was forced to withdraw this invitation as it received phone calls from people threatening to pelt the youth with missiles on the day. The head of the New South Wales RSL was quoted as saying that "the people who made these threats ought to be bloody ashamed of themselves".

In 1990, during heated political times around the Meech Lake Accord, the flag of Quebec was desecrated by residents of Brockville, Ontario opposed to Quebec's language laws. Televised images of individuals stepping on the Quebec flag were played in Quebec and contributed to the deterioration in relations between Quebec and English Canada. The incident, seen as a metaphor of Canada's perceived rejection of Quebec (and of Quebec's distinctiveness in the demise of the Meech Lake Accord) was invoked by Quebec nationalists during the run-up to the 1995 referendum on Quebec independence and is still remembered today.
In 2003, Baptists from Canada and the United States staged a flag burning of the Canadian Flag outside of the Supreme Court of Canada in Ottawa, Ontario. This was to protest same-sex marriage that was being decided with the Canadian court system.

In 2003, a Workers Party of New Zealand member Paul Hopkinson, a Wellington schoolteacher, burned the Flag of New Zealand as part of a protest in Parliament grounds at the New Zealand Government’s hosting of the Prime Minister of Australia, against the background of Australia’s support of the United States in its war in Iraq. Hopkinson was initially convicted of destroying a New Zealand flag with intent to dishonor it, but appealed against his conviction.
On appeal, his conviction was overturned on the grounds that the law had to be read consistently with the right to freedom of expression under the New Zealand Bill of Rights Act 1990. This meant that his actions were not unlawful because they were done in the context of a protest; however, outside of a protest, the same actions would still have been illegal. This somewhat unusual result was due in part to the fact that the New Zealand Bill of Rights Act does not overrule other laws. Hopkinson was the first person charged under the Flags, Emblems and Names Protection Act. Shortly after his successful appeal, Hopkinson again burned a New Zealand flag and was arrested once more, this time for disorderly conduct. This subsequent charge was later dropped following legal advice that, because of the appeal court's decision, Hopkinson's action would again have been justifiable as a form of free expression or free speech.
The Portuguese Penal Code (article 323rd) also forbids the desecration of foreign symbols: "Who publicly, by means of words, gestures or print publication, or by other means of public communication, insults the official flag or other symbol of sovereignty of a foreign State or of an international organization of which Portugal is a member shall be punished with up to one year imprisonment or a fine of up to 120 days." This article applies under two conditions (article 324th): that Portugal maintains diplomatic relations with the insulted country, and that there is reciprocity (i.e., that the insulted country would also punish any insult against Portuguese symbols of sovereignty, should they occur there).
In Romania, according to the article 236 of the penal code, any manifestation which expresses contempt for the Romanian symbols (according to the constitution, these are the flag, national day, anthem and coat-of-arms) is punished by imprisonment, from 6 months to 3 years, while the contempt for the symbols of Romanian authorities is also punished by imprisonment, from 3 months to 1 year, or by fine.
This law has been seen in a report of the Press Monitoring Agency, a project financed by the Open Society Institute, as being a potential danger to the freedom of expression because of its vague terms, because it can incriminate opinions.
English, Scottish and Welsh law does not have any concept of "flag desecration", however the law in Northern Ireland has varied since its foundation in 1921. The Union Flag of the United Kingdom and the tricolour of the Republic of Ireland are often defaced or burnt in Northern Ireland as a political provocation or as a protest. The Flags and Emblems Act of 1954 of the Northern Ireland Parliament, effective until repeal in the 1980s, made illegal the display of a flag likely to cause a "breach of the peace" and made it an offence to interfere or threaten to interfere with the display of "a Union flag." More recently, there has been controversy in Northern Ireland over which flags (if any) to fly over government buildings.
The Queen's Colours and Regimental Colours are a very important symbol for a British Army regiment and for many regiments in the Commonwealth which have inherited the British Army's traditions. In a Line Regiment the Colour stand consists of these two flags, and damage to such a symbol would be a considered a great insult to the regiment by its members. In the past, when Colours were carried into battle, the seizure of an enemy Colour or the defence of the regiment's own Colours have ranked among any British regiment's finest moments. Examples include Sergeant Ewart's capture of the French 45th Ligne Eagle standard during the charge of the Scots Greys at the Battle of Waterloo; and the actions of Lieutenants Coghill and Melvill, who were both killed in their failed attempt to save the Queen's Colour at the Battle of Isandlwana, and for which they were awarded Victoria Crosses posthumously.
In the British armed forces, it is usual for flag-bearers to lower flags and standards, even Queen's and Regimental Colours, so that they are draped on the ground, as part of a royal salute or during the two-minute silence on Remembrance Sunday. This mark of respect, known as vailing, is not considered to be a desecration of the colours.
The flag of the United States has sometimes been used in symbolic defacement, often in protest of the policies of the American government, both within the country and abroad.
In 1862, during the Union army's occupation of New Orleans in the American Civil War, the military governor, Benjamin Franklin Butler, sentenced William B. Mumford to death for removing an American flag. Today, defacing a flag is an act of protected speech under the First Amendment to the United States Constitution, as established in Texas v. Johnson, 491 U.S. 397 (1989), and reaffirmed in U.S. v. Eichman, 496 U.S. 310 (1990).
After these decisions, several "flag burning" amendments to the Constitution have been proposed. On June 22, 2005, a flag burning amendment was passed by the House with the needed two-thirds majority. On June 27, 2006, the most recent attempt to pass a ban on flag burning was rejected by the Senate in a close vote of 66 in favor, 34 opposed, one vote short of the two-thirds majority needed to send the amendment to be voted on by the states.
The United States Flag Code lists many guidelines for the use and display of the flag. For example :
American sports teams often wear an American flag on their uniforms.
The ritualized burning of the American flag is considered an appropriate way to dispose of a damaged or soiled flag. Flags are burned in retirement ceremonies by the American Legion, Girl Scouts of America, Boy Scouts, The Veterans of Foreign Wars, the Daughters of the American Revolution, and the Sons of the American Legion.
Flying an American flag upside down is not necessarily meant as political protest. The practice has its origin in a military distress signal; displaying a flag in this manner is "a signal of dire distress in instances of extreme danger to life or property"
; it has been used by extension to make a statement about distress in civic, political, or other areas. Upside-down flying of the flag was ruled constitutional in Spence v. Washington, a 1974 Supreme Court ruling.
