Legal protection of access to abortion
Governments sometimes take measures designed to afford legal protection of access to abortion. Such legislation often seeks to guard facilities which provide induced abortion against obstruction, vandalism, picketing, and other actions, or to protect patients and employees of such facilities from threats and harassment.
Another form such legislation sometimes takes is in the creation of a perimeter around a facility, known variously as a "buffer zone", "bubble zone", or "access zone". This area is intended to limit how close to these facilities demonstration by those who oppose abortion can approach. Protests and other displays are restricted to a certain distance from the building, which varies depending upon the law, or are prohibited altogether. Similar zones have also been created to protect the homes of abortion providers and clinic staff.
Bubble zone laws are divided into "fixed" and "floating" categories. Fixed bubble zone laws apply to the static area around the facility itself, and floating laws to objects in transit, such as people or cars.

 Laws in Canada
One country in which "buffer zone" laws have been enacted is Canada. One of the country's provinces and territories has passed a law intended to protect medical facilities that provide induced abortion:
- British Columbia: 10 metre fixed buffer zone around a doctor's office, 50 metre fixed buffer zone around a hospital or clinic, and 160 metre fixed buffer zone around an abortion provider or clinic worker's home. The Access to Abortion Services Act, enacted in 1995, refers to this area as an "access zone". It prohibits protesting, sidewalk counseling, intimidation of or physical interference with abortion providers or their patients inside of this space. The provisions against protesting and sidewalk counselling were repealed on January 23, 1996, as violating the Canadian Charter, but were both restored in October of the same year.
Access zone legislation has also been passed at the level of local government in Canada:
- Calgary, Alberta: fixed buffer zone which requires protesters to remain across the street from a clinic in Kensington. Established in 1991, the injunction also limits the number of pro-life demonstrators who carry signs, or pray. It was first challenged by Michael O'Malley of Campaign Life Coalition in 1997, and again in 2000, but a judge upheld it both times.
- Toronto, Ontario: 500 feet fixed buffer zone around doctors' homes, 25 feet (7.6 m) fixed buffer zone around doctors' offices, 60 feet (18 m) fixed buffer zone around two clinics in the Cabbagetown and Scott districts, 30 feet (9.1 m) fixed buffer zone around another clinic, and 10-foot (3.0 m) floating buffer zone around patients and staff. The injunction was granted on August 30, 1994.
 Laws in South Africa
The Choice on Termination of Pregnancy Act prohibits anyone from "preventing the lawful termination of a pregnancy" or "obstructing access to a facility for the termination of a pregnancy", imposing a penalty of up to ten years' imprisonment.
 Laws in the United States
At the federal level in the United States, the Freedom of Access to Clinic Entrances Act (FACE), makes it an offense to use intimidation or physical force – such as forming a blockade – in order to prevent a person from entering a facility which provides reproductive healthcare or a place of worship. The law also creates specific penalties for destroying, or causing damage to, either of these types of building.
California, New York, and Washington have each established their own version of FACE. Other states have instituted several different kinds of measures designed to protect clinics, their employees, and patients:
- 11 states make it illegal to obstruct the entrance to a clinic: California, Kansas, Maine, Maryland, Minnesota, Montana, Nevada, New York, North Carolina, Oregon and Washington.
- Six states prohibit making threats toward a clinic's staff or patients: California, Michigan, New York, North Carolina, Washington, and Wisconsin. Two states, Maine and Washington, also ban harassment by telephone.
- Four states ban property damage to a clinic: California, Oregon, New York, and Washington.
- One state, Maine, has enacted a noise regulation pertaining to activity outside of a clinic, and also made it an offense to intentionally release a substance with an unpleasant odour inside of it.
- One state, North Carolina, prohibits weapon possession during a demonstration outside of a clinic.
In the February 2003 case, Scheidler v. National Organization for Women, the Supreme Court of the United States ruled that pro-life activists could not be prosecuted under the Racketeer Influenced and Corrupt Organizations Act (RICO), a law drafted to counter organized crime, or the Hobbs Act, a law intended to address economic damages caused by extortion. The Court reaffirmed this holding on February 28, 2006 in a unanimous decision, although only 8 Justices participated in the ruling, because Samuel Alito had not yet been confirmed.
 "Buffer zone" laws
- Colorado: 100 feet fixed and eight feet floating. After being enacted in 1993, the "floating" provision was first challenged in 1995, when three pro-life activists suggested that it violated their right to freedom of speech. Although upheld in a trial court and by the state's appeals court, the Supreme Court of Colorado would not hear the case, so the petitioners took their case against Colorado's floating buffer law to the Supreme Court of the United States. In February 1997, considering its ruling against a floating buffer zone in the case Schenck v. Pro-Choice Network of Western New York, the Supreme Court requested that the appeals court of Colorado re-examine their state's law. It was upheld again, and in February 1999, the Supreme Court of Colorado agreed with the holdings of the lower court. In the 2000 case Hill v. Colorado, the "floating" provision was again appealed before the federal Supreme Court, where it was upheld 6-3.
- Massachusetts: 35 feet fixed buffer zone enacted in 2007. Massachusetts Attorney General Martha Coakley’s Office defended the constitutionality of the statute in the federal court proceedings. In May 2007, Attorney General Coakley testified before the Legislature in support of the passage of the legislation. The buffer zone law was signed by Governor Deval Patrick and took effect on November 13, 2007. Attorney General Coakley successfully defended the statute before the U.S. Court of Appeals for the First Circuit, which affirmed the constitutionality of the Commonwealth's buffer zone law on July 8, 2009. The 2007 law changed the 2000 law, which provided for an 18 feet fixed buffer zone and six feet floating buffer zone. Enacted on November 10, 2000, this law was struck down by U.S. district judge Edward Harrington soon afterward because he felt there was an unacceptable discrepancy in the floating buffer zone being applied to pro-life protesters but exempted from clinic workers. The law was restored in August 2001 by a federal appeals court.
- Montana: 36 feet (11 m) fixed buffer zone and eight feet floating buffer zone.
- Buffalo and Rochester, New York: 15 feet fixed and 15 feet (4.6 m) floating around four clinics in two cities. The buffer zone resulted from an injunction issued by the U.S. district court in response to a federal lawsuit filed against 50 individuals and three pro-life organizations, including Operation Rescue, by three doctors and four clinics. The law was challenged in the 1997 case court case, Schenck v. Pro-Choice Network of Western New York, by pro-life activist Paul Schenck. The case came before the Supreme Court, where Justices, in considering Madsen v. Women’s Health Center, ruled 8-1 to uphold the constitutionality of the fixed buffer zone, but not that of a floating buffer zone.
- Melbourne, Florida: 36 feet fixed buffer zone around a clinic, 300 feet (91 m) floating buffer zone around patients, and 300 feet (91 m) buffer zone around the homes of the clinic's employees. The injunction also regulated noise levels outside of the clinic and prevented demonstrators from displaying images which could be seen from inside. It was upheld in full by the Supreme Court of Florida but came before the federal Supreme Court in Madsen v. Women’s Health Center in 1994. The Court upheld the fixed buffer zone, and the noise regulation around clinics and in residential areas, but rejected the floating buffer zone, residential buffer zone, and prohibition against displaying images.
- Pittsburgh, Pennsylvania: 15 feet fixed buffer zone and eight feet floating buffer zone. The statute was approved by the Pittsburgh City Council in December 2005. In 2009 a three judge appeals court panel found in Brown v. Pittsburgh that while either a fixed buffer or a floating buffer alone is constitutional, this combination of buffers is "insufficiently narrowly tailored," and thus unconstitutional.
- Vallejo, California: fixed buffer zone which requires protesters to remain across the street from a clinic enacted in 1991. After the Supreme Court of California upheld the injunction, the case was taken to the federal Supreme Court in October 1994, but was remanded to the state court due to the recent Madsen v. Women's Health Center decision. The California Supreme Court again upheld the buffer zone in July 1995. On March 17, 1997 the case reached the federal Supreme Court as Williams v. Planned Parenthood Shasta-Diablo, and Justices voted 6-3 to decline the case.
- West Palm Beach, Florida: 20 feet buffer zone and noise ordinance approved in September 2005. U.S. District Judge Donald Middlebrooks found the law to be an infringement of the right to free speech on April 11, 2006, and ordered that it be enjoined, but upheld the regulation against excessive noise.
- Chicago, Illinois: 8 foot floating buffer zone within 50 feet of clinic entrance enacted in November 2009. 
Supporters of such laws claim that these zones are necessary to ensure that women have access to abortion. They argue that a buffer zone helps to prevent blockading of a clinic's entrance, to protect the safety of patients and staff, and to ensure that clients do not feel intimidated, distressed, or harassed by the presence of pro-life activists.
Some traditional free speech advocates such as the British Columbia Civil Liberties Association have cautiously sided in favour of limited "bubble zones" around abortion clinics on the basis that patients have a medical right to privacy when receiving confidential legal medical procedures that is compromised if protesters identify patients for the purpose of publicly shaming or intimidating them.
Some pro-choice activists have also argued that anyone convicted of anti-abortion violence should be permanently banned from protesting outside abortion clinics. Professor Jacob M. Appel of New York University has argued that "[m]uch as we do not permit convicted pedophiles to teach kindergarten or convicted hijackers to board airplanes, common sense dictates that individuals who have been imprisoned for plotting violence against abortion clinics should never again be permitted anywhere near such facilities.".
Those who oppose the creation of such legislation contend that "bubble zones", by limiting the ability to protest peacefully, represent an infringement upon their rights to freedom of expression and freedom of assembly.
