Mobile phones have become part of everyday life. They contain private conversations, banking information, photographs, emails, social media accounts, business records, and personal memories. For many people, a smartphone is almost like a digital extension of their private lives.

Because of this, an important legal question continues to arise in Ghana:
Can the police search your phone without a warrant?

The issue has become increasingly important as criminal investigations rely more on electronic evidence and digital communication.

The 1992 Constitution guarantees the right to privacy under Article 18(2). The provision protects the privacy of a person’s home, property, communication, and correspondence except in situations permitted by law and necessary in a democratic society.

In today’s digital world, many legal observers argue that smartphones should be treated almost like a person’s “digital home” because they contain enormous amounts of personal information.

This means police powers during investigations are not unlimited simply because information is stored electronically.

One important issue is what happens when evidence is obtained through a violation of a person’s constitutional right to privacy.

In the Supreme Court case of Raphael Cubagee v Michael Asare, the court examined whether evidence obtained in breach of constitutional rights should automatically be excluded by courts.

The Supreme Court rejected the idea that evidence must always be excluded automatically whenever a constitutional right is violated. Instead, the court adopted what is known as the discretionary exclusionary rule.

Gabriel Scott Pwamang, who sat on the case as a Justice of the Supreme Court, explained that human rights enforcement is not always absolute and that courts must sometimes balance public interest with constitutional protections.

The effect of the decision is that Ghanaian courts may examine each situation individually rather than applying a fixed rule in every case.

In simple terms, evidence obtained through a privacy violation may still become an issue for judicial interpretation depending on the circumstances of the case.

One of the most important Ghanaian decisions involving phone searches and digital privacy is the case of Edmund Addo (Edmund Addo v IGP & A-G).

In 2016, the police arrested him and seized his mobile phone, laptop, internet modem, and hard drive. According to the facts presented before the court, the police demanded passwords to access the devices, but he refused.

The police later engaged IT experts in an attempt to access the devices and retrieve information for prosecution purposes.

The matter eventually ended up before the High Court in Accra.

Lawyer Justice Srem-Sai argued that although the police had custody of the devices, they had no legal authority to search through the contents without first obtaining a court warrant.

He argued that the conduct of the police violated the applicant’s constitutional rights to privacy and fair trial.

The Attorney-General, however, argued that criminal investigations could justify limitations on privacy rights.

The High Court, presided over by Anthony Yeboah, ruled in favour of the applicant.

The court held that the conduct of the police amounted to a violation of the applicant’s constitutional rights to privacy and fair trial.

The court also ordered the police to submit the seized electronic gadgets to the registrar of the trial court.

The decision became one of the most important judicial pronouncements on digital privacy rights in Ghana because it drew a distinction between:

• seizing a device,
• and actually searching through its contents.

Another important case touching on constitutional rights in criminal investigations is Okorie v Republic.

In that case, the police obtained a statement from the accused person without informing him of his constitutional right to counsel. The court held that the statement had been obtained in violation of the accused person’s constitutional rights and was therefore inadmissible in evidence.

The decision reinforced the principle that constitutional protections continue to apply even during criminal investigations and prosecutions.

The legal position appears to be that police officers may seize a phone during investigations under certain circumstances, especially where they reasonably suspect it contains evidence connected to a crime.

However, accessing the contents of the device is a different matter.

The Edmund Addo case strongly suggests that police officers generally require judicial authorisation or a court warrant before searching through the contents of a person’s phone, laptop, or other electronic device.

In practical terms:

• police may seize a device,
• but searching messages, photos, emails, applications, or files without proper legal authority could amount to a violation of constitutional privacy rights.

This area of law continues to evolve as technology changes.

The Edmund Addo case raised important questions about whether police can compel individuals to disclose passwords or grant access to encrypted devices without court approval.

As digital investigations increase, Ghanaian courts may continue to define the limits of police powers regarding passwords, biometric access, and electronic privacy.

Many people casually hand over their phones during police encounters without understanding the legal implications involved.

Modern smartphones contain highly sensitive information about personal lives, finances, relationships, businesses, and communication.

Unrestricted access to such devices without proper safeguards could easily lead to abuse or violations of constitutional rights.

The law therefore attempts to balance:

• the powers of the police to investigate crime,
• and the constitutional rights and freedoms of citizens.

Under Article 19(2) of the Constitution, every person charged with a criminal offence is presumed innocent until proven guilty or until the person pleads guilty.

This means constitutional protections do not disappear merely because a person becomes a suspect.

Article 18(2) also makes it clear that privacy rights may only be limited “in accordance with law” and for purposes such as public safety or crime prevention.

In other words, even where police investigations are necessary, the law still requires proper legal procedures to be followed.

The growing importance of electronic evidence means Ghanaian courts will likely continue shaping the boundaries between criminal investigations and digital privacy rights for years to come.
