Who Defines the Limits of Free Speech?

Freedom of expression is constrained in different ways by the state, the courts and society. Confusing these forms of pressure obscures where the greatest dangers lie.

Freedom of expression is one of the most fundamental civil and political rights. It is protected by international treaties, including the European Convention on Human Rights, as well as by national constitutions around the world.

Yet few rights provoke such frequent and bitter disagreement. Disputes over speech arise in criminal investigations, civil proceedings, political debate and public campaigns. Each involves a different form of restraint, and each must be judged according to a different standard.

The state may intervene when speech is thought to cross the threshold into criminal conduct. Courts may restrict statements that unlawfully damage the rights of identifiable individuals. Society, meanwhile, imposes consequences of its own through criticism, ridicule and reputational pressure.

These forms of restraint are not interchangeable. Failing to distinguish between them makes it harder to identify when legitimate accountability becomes an abuse of power.

When Tweets Become Police Matters

The most direct threat to freedom of expression arises when the state uses its coercive powers against individuals for what they have said.

British writer and comedian Graham Linehan was arrested at London’s Heathrow Airport in September 2025 after returning from Arizona. He had long campaigned against what he regarded as the erosion of free speech in the United Kingdom.

Five armed police officers detained him over three posts on social media platform X concerning transgender issues. He was suspected of inciting hatred under the Public Order Act and held for about 12 hours.

The first post showed a photograph of a transgender rally with the caption: “A photo you can smell.” He followed it with another post reading: “I hate them. Misogynists and homophobes. F*** em.” His third post stated: “If a trans-identified male is in a female-only space, he is committing a violent, abusive act. Make a scene, call the cops and, if all else fails, punch him in the balls.”

Linehan later said that the final post had been intended as a provocative and ill-judged joke rather than a genuine call for violence.

Following his interrogation, he was taken to hospital after officials became concerned about his blood pressure. He was later released on bail, initially under conditions that prevented him from posting on X.

Linehan subsequently brought a civil claim against the Metropolitan Police with the support of the Free Speech Union. The case ended in an out-of-court settlement reportedly worth £25,000 (about $34,000).

A Metropolitan Police spokesperson said: “We recognise the considerable distress caused to Mr Linehan, and have offered our sincere apologies.”

A month after his arrest, the Metropolitan Police announced that it would no longer investigate non-crime hate incidents, allowing officers to “focus on matters that meet the threshold for criminal investigations”. The force also dropped its investigation into Linehan.

The outcome did not create a legal precedent in the formal sense. It may nevertheless influence how police approach comparable cases in future.

Official statistics suggest that the Linehan case was far from isolated. In 2023, police in Britain arrested more than 12,000 people over allegedly offensive online messages, an average of about 30 arrests a day.

The power to arrest is among the most serious powers available to the state. It should therefore be used only where there is a clear and credible suspicion that the threshold for criminal conduct has been crossed. Offensive, provocative or tasteless speech is not automatically criminal speech.

When Political Speech Damages Individual Rights

Restrictions imposed by civil courts are different from police action. Their purpose is not to punish unpopular opinions, but to protect individuals from false or unsupported allegations that damage their reputations and personal rights.

A series of cases in Slovakia involving a group of police investigators known as the Curilla group illustrates that distinction.

The group, named after investigator Jan Curilla, was suspended from duty after its members were accused of interfering in investigations into several high-profile cases under the previous government. Since then, the investigators have brought a number of legal actions against politicians who publicly described them as criminals.

Former speaker of parliament Boris Kollar was ordered in a final ruling to pay Curilla €50,000 ($58,000) in damages and issue a public apology.

Kollar had described the investigators as the “Curilla mafia”. The court found that the remark had unjustifiably infringed Curilla’s personal rights by associating him with organized crime and disregarding the presumption of innocence.

The court also stressed that Kollar had made the statement in his official capacity as speaker of parliament rather than merely as a private citizen. His position gave his words greater authority and reach.

The investigators have also sued Interior Minister Matus Sutaj Estok over statements in which he described them as criminals and compared them with convicted offenders.

They initially obtained a default judgment after the minister failed to respond because he had not checked his email. The ruling ordered him to pay more than €100,000 ($116,000) in damages and apologize publicly. An appeals court later overturned the judgment, and the case will now proceed to a full hearing.

The group also obtained a non-final judgment against MP Michal Bartek, who was ordered to apologize for publicly claiming that the investigators had “allegedly handpicked the judge for their case”. The court did not award the more than €80,000 ($93,000) in damages they had sought.

Further defamation lawsuits have been filed against Prime Minister Robert Fico and several other MPs over similar remarks.

These cases do not establish that politicians may not criticize police officers, investigations or criminal proceedings. Political speech enjoys broad protection, particularly when it concerns matters of public interest.

That protection does not, however, give elected officials an unrestricted right to present identifiable individuals as criminals without an established factual basis. An indictment does not amount to a conviction, and political rhetoric does not remove the obligation to respect the presumption of innocence.

The cases therefore concern a boundary different from the one raised by Linehan’s arrest. The issue is not whether the state may punish an unpopular opinion, but whether one person’s speech unlawfully harms the rights of another.

The final rulings are likely to influence how Slovak courts balance political expression against reputation and personal dignity.

When Public Criticism Becomes Social Pressure

Not every restriction on expression comes from police officers or judges. Society also imposes powerful sanctions through criticism, ridicule, exclusion and reputational damage.

These consequences are not censorship in the legal sense. They are often themselves exercises of free expression. Yet they can still create a climate in which people avoid lawful speech, associations or professional engagements for fear of public punishment.

Musician Marian Cekovsky encountered this form of pressure after performing at national celebrations marking the Feast of Sts Cyril and Methodius at Devin Castle.

The event had been organized by the government, and Cekovsky received a fee for his performance. Both his participation and the amount he was paid subsequently became subjects of public controversy.

Among his critics was politician and singer Dorota Nvotova, who accused him of having “collaborated with the political establishment” by appearing at the celebrations.

Other members of the artistic and progressive community also criticized and mocked him for accepting a paid engagement at an event they regarded as politically contentious.

Cekovsky then became the target of sustained hostility on social media, including insults and ridicule. His critics defended their response both as part of the “fight against crooks in politics” and as an exercise of their own freedom of expression.

They were entitled to criticize his decision. Performing at a government event does not place an artist beyond political scrutiny, particularly when public funds are involved.

At the same time, criticism should not automatically become a campaign of personal humiliation. When disagreement turns into demands for professional exclusion or attempts to make lawful participation socially unacceptable, it may narrow the range of choices that artists and other public figures feel free to make.

That does not make such pressure equivalent to arrest, prosecution or a court judgment. The distinction is essential. Public condemnation is not state censorship.

It can nevertheless contribute to a culture in which people remain silent or avoid lawful activities because they fear the reputational consequences.

Different Limits Require Different Standards

The limits of freedom of expression are not drawn by a single institution.

Police decide when speech may justify a criminal investigation. Courts determine when statements unlawfully damage the rights of identifiable individuals. Society imposes reputational consequences through criticism and public pressure.

Each of these mechanisms may be legitimate. Each may also be abused.

A police force may treat offensive speech as criminal without sufficient justification. A politician may disguise a damaging allegation as political opinion. A public campaign may turn legitimate criticism into sustained personal intimidation.

A democratic society must therefore distinguish carefully between speech that is criminal, speech that unlawfully harms another person and speech that is merely offensive, provocative or unpopular.

The right to speak does not guarantee freedom from disagreement or criticism. Nor does the existence of legal limits give the state unlimited authority to determine which opinions may be expressed.

The real task is not to eliminate every boundary, but to ensure that each boundary is drawn by the right institution, according to the right standard and with sufficient respect for individual liberty.
