Switzerland’s New Stalking Offence: Criminal Protection Against Persistent Harassment Takes Effect
Editorial note: This is a current-affairs article based on official Swiss sources, legal commentary, and public-service reporting. It is not individual legal advice. Anyone facing stalking should contact the police, a victim-support service, or a qualified lawyer.
On January 1, 2026, Switzerland brought a new criminal provision on stalking into force. The reform adds Article 181b to the Swiss Criminal Code and makes persistent harassment, known in Swiss legal terminology as Nachstellung, a standalone criminal offence.[1] [2]
The change followed a parliamentary decision of June 20, 2025. After the referendum period expired without a referendum, the Federal Council decided on November 19, 2025, that the amendment would take effect at the start of 2026.[1] The government described the reform as a way to improve protection for people whose freedom, personal security, and ability to organize their everyday lives are seriously affected by obsessive harassment.
Under the new provision, a person who persistently follows, harasses, or threatens another person in a manner capable of significantly restricting that person’s freedom to shape their life may face a custodial sentence of up to three years or a monetary penalty.[2] The offence is generally prosecuted only after the affected person files a criminal complaint. Legal commentary identifies a three-month period for filing that complaint under Article 31 of the Criminal Code.[3]
The reform addresses a practical gap. Before Article 181b, stalking could be prosecuted through a combination of broader offences—such as threats, coercion, trespass, or unlawful use of communications—but Swiss law did not contain one provision designed specifically for a repeated pattern of intrusive conduct.[4] The new rule gives prosecutors and courts a legal category that focuses on the cumulative effect of conduct rather than treating every incident as an isolated event.
What counts as stalking under Article 181b?
The law does not establish a fixed number of acts that automatically turns unwanted attention into a crime. Instead, persistence is assessed from the overall pattern. According to Swiss legal analysis, repeated following, waiting near a person, surveillance, unwanted messages or visits, intimidating behavior, intrusion into private space, and conduct directed at property can fall within the provision when they significantly restrict the victim’s freedom of action.[3]
The key issue is not whether one unpleasant interaction occurred. It is whether a series of intentional acts creates a level of pressure that changes how the targeted person lives. A victim may stop visiting certain places, alter commuting routes, avoid social activities, change contact details, install security measures, or modify online behavior. The conduct may also produce fear, withdrawal, or a constant need to anticipate the perpetrator’s next move.
The wording is technology-neutral. That matters because stalking can cross physical and digital boundaries at the same time. Repeated messages, location monitoring, impersonation, unwanted contact through multiple accounts, publication of private information, and digital surveillance may be relevant when they form part of a persistent course of conduct.[3]
Element of the offence | Practical meaning |
Persistent conduct | A pattern of acts assessed together, rather than one isolated incident |
Following, harassment, or threats | Physical surveillance, repeated contact, intimidation, or interference with private life |
Significant restriction of life choices | The conduct affects where, how, or with whom the victim can live safely |
Intent | The perpetrator must act intentionally; Swiss commentary also recognizes contingent intent |
Complaint-based prosecution | The affected person generally must file a criminal complaint within the applicable period |
Possible penalty | Up to three years’ imprisonment or a monetary penalty |
Why the reform matters to victims
Stalking is often difficult to capture through conventional criminal categories. A single message may appear harmless. A single appearance outside a workplace may not, on its own, prove a serious offence. The danger can become visible only when the events are documented as a connected sequence.
The Federal Council has emphasized that the consequences may be psychological, social, and economic.[1] A person may lose sleep, miss work, incur security expenses, withdraw from relationships, or feel unable to use ordinary public spaces. The effect is a loss of practical autonomy: the victim’s decisions are shaped not by free choice but by the need to avoid the person who is pursuing them.
By naming the pattern directly, Article 181b may improve the way complaints are recorded and investigated. Police officers can assess whether separate incidents form one course of conduct. Prosecutors can request evidence that shows frequency, escalation, and impact. Courts can consider the totality of the behavior rather than asking whether each individual act independently satisfies a different criminal provision.
The complaint requirement also places a significant responsibility on the victim. A person must recognize the legal significance of the behavior, gather evidence, identify the suspect where possible, and act within the applicable time limit. Fear, exhaustion, financial dependence, language barriers, or an ongoing relationship with the perpetrator may make that difficult.
Victim-support organizations and police guidance will therefore remain important. A new offence does not automatically make reporting safe or simple. Its effectiveness will depend on whether authorities respond early, preserve digital evidence, assess escalation risks, and explain available protection measures in accessible language.
The legal threshold: persistence and substantial interference
The law’s flexibility is intentional, but it also creates interpretive questions. There is no mechanical test stating that five messages, three visits, or two threats always meet the threshold. Courts will need to determine whether the conduct was persistent and whether it was capable of significantly restricting the victim’s freedom to shape their life.
That approach allows the law to address different forms of stalking. A perpetrator may send hundreds of messages, appear repeatedly at a home, monitor a former partner, contact relatives and employers, or combine physical surveillance with online intimidation. A rigid numerical rule could miss serious cases that develop through varied tactics.
At the same time, the prosecution must distinguish criminal persistence from ordinary interpersonal conflict, unsuccessful communication, or a single offensive incident. The requirement of intent and significant interference provides safeguards against treating every unwanted interaction as stalking. Evidence of repetition, context, escalation, threats, surveillance, fear, and behavioral changes will likely be central to future cases.
The technology-neutral approach raises a related evidentiary challenge. Digital conduct can be anonymous, automated, rapidly deleted, or distributed across platforms located in different countries. Investigators may need account records, device data, screenshots, witness statements, and platform cooperation. Courts will also need to assess whether allegedly manipulated material accurately reflects the communications and who controlled the relevant accounts.
The parliamentary and social debate
The reform reflects a wider debate about how criminal law should respond to coercive patterns that often occur after separation, in intimate relationships, or during conflicts involving rejection and control. Advocates for stronger protection argue that the law should intervene before a pattern escalates into physical violence. A dedicated offence can signal that repeated intrusion is not merely irritating behavior but a potential attack on personal freedom.[1] [4]
Some caution is still necessary. Criminal law should not be the only response. Victims may also need emergency protection, safe housing, workplace support, counseling, digital-security assistance, and civil measures restricting contact. A complaint may start a criminal process, but it may not immediately stop the perpetrator from appearing, calling, or posting material online.
Implementation will also test coordination among cantonal police forces, prosecutors, courts, victim-support offices, and digital platforms. Switzerland’s federal structure means that national legislation is applied through institutions operating in different cantons and linguistic regions. Consistent training will be important so that victims receive comparable information and patterns are not minimized because each incident occurred in a different place or through a different medium.
What the new rule does—and does not—do
Article 181b does not create automatic imprisonment for every person accused of stalking. The maximum penalty is three years, while the actual sentence will depend on the facts, culpability, evidence, and applicable sentencing rules.[1] [3] A criminal complaint is also not the same as a conviction. Authorities must investigate, establish the elements of the offence, and respect the procedural rights of the accused.
The provision does, however, change the legal vocabulary available to victims and authorities. It recognizes that a sequence of individually modest acts can become seriously harmful when combined. That recognition is particularly relevant in the digital age, where a perpetrator can maintain continuous contact without being physically present.
The complaint-based structure means that public awareness is essential. Victims should preserve messages, call records, photographs, dates, witness names, platform URLs, and evidence of changes made to daily routines. They should avoid putting themselves at additional risk to collect proof. A victim-support service or lawyer can help determine how to document conduct and where to report it.
A new benchmark for personal freedom
Switzerland’s stalking provision is a focused change to the Criminal Code, but its practical meaning will develop through police practice, prosecutorial decisions, and court interpretation. Its success will be measured not only by convictions or sentence totals but also by whether victims are taken seriously before harassment escalates, whether digital and physical conduct are assessed together, and whether complaint procedures are accessible in practice.
The reform sends a clear legal message: persistent unwanted pursuit can be an offence even when no single act tells the whole story. By treating obsessive harassment as a specific form of criminal conduct, Swiss law gives personal autonomy and everyday freedom a more direct place in the protection offered by the criminal justice system.
