In the case Up-1134/18 of 12th May 2022, ECLI:SI:USRS:2022:Up.1134.18, the Slovenian Constitutional Court addressed for the first time the issue of worker’s right to privacy at the workplace (during the performance of work). On the one hand, the worker can reasonably expect a certain degree of privacy in the workplace – on the other hand, the employer also has the right to supervise the worker under certain conditions (and in specific cases). The issue at hand is also directly related to civil procedural law, since the termination of the worker’s employment contract may be based precisely on evidence obtained by interfering with the worker’s right to privacy. Moreover, in subsequent proceedings before the employment tribunal (before which the worker challenges the termination of his employment contract), the question of whether evidence obtained by interfering with the worker’s right to privacy may be used in the court proceedings arises.
In the present case, the appellant alleged in her constitutional complaint that inadmissible evidence was used in the proceedings for the extraordinary termination of the employment contract and in the subsequent court proceedings. The evidence was obtained by means of covert investigative measures (covert video surveillance and a covert trap with marked banknotes) in violation of the legal norms on individual’s personal data protection. The appellant thus submitted that she was unlawfully monitored in the performance of her work, which constituted an interference with her right to privacy at work, protected by Article 35 of the Constitution. The appellant submitted that the court should have excluded from the case file the video and the detective’s report, which had been prepared in violation of the appellant’s constitutional rights (case Up-1134/18, para. 2).
The appellant unsuccessfully challenged before the lower courts the extraordinary dismissal of her employment contract, alleging that the employer had unjustifiably interfered with her right to privacy. The appellant allegedly took out 20 EUR from the patient’s drawer, which was foreign property, and stole it. The above was allegedly established by installing a recording device and a trap with marked banknotes in the patient’s drawer (case Up-1134/18, para. 1).
In the present case, the Constitutional Court thus dealt with the question of whether such an investigation at the workplace constituted a violation of the worker’s right to privacy under Article 35 of the Slovenian Constitution.
The Court concluded that there was an interference with the worker’s right to privacy. The next question was whether the interference with the worker’s right to privacy passes the proportionality test.
The Constitutional Court relied on the case law of the ECtHR, namely Barbulescu v. Romania (2017) and Lopez Ribalda and others v. Spain (2019), as relevant criteria for the assessment. The Constitutional Court summarises that in these cases, the ECtHR took into account the following as relevant criteria: workers’ information about the possibility of surveillance; the scope of the surveillance and the intensity of the interference with the right to privacy; the legitimate reasons for carrying out the surveillance; the possible existence of the possibility of surveillance by less invasive means; the extent of the consequences for the affected worker; and the existence of safeguards in the national legislation to prevent abuses. Importantly, these are only criteria for assessment and not exclusionary conditions. The Constitutional Court emphasises that if any of the above criteria are missing in the exercise of control – greater weight must be given to the safeguards arising from the other criteria (case Up-1134/18, para. 13).
As regards the criterion of information to the workers, the Court notes that the appellant was not informed in advance of the recording device and the cash trap in the drawer. As the information criterion is not met, the other criteria must consequently be given greater weight in weighing the proportionality of the interference (case Up-1134/18, para. 15).
Furthermore, the Constitutional Court found that in the present case, there were particularly justified legitimate reasons for the measure taken to monitor workers in order to detect the perpetrator of repeated thefts. The employer and the workers also had the duty to protect the rights of the protected persons. The measure was also appropriate, as the installation of a recording device and a cash trap in the drawer of a bedside locker is clearly a measure which can detect a thief (case Up-1134/18, para. 17).
Of particular importance was the Court’s assessment of whether the measure was necessary or whether less invasive measures could have been taken. The Court notes that the employer first attempted to report the cases to the police but was unsuccessful as the thefts continued. Having regard to the circumstances of the case, the Constitutional Court notes that no other equally effective means were available which would have protected the property and privacy of the patients in the same way, and which would have interfered to a lesser extent with the appellant’s right to privacy. Surveillance by supervisors or colleagues or overt video surveillance did not have the same chance of success in detecting a thief, given the way the thefts were carried out. Moreover, the covert surveillance was limited in space and time to the minimum extent possible. Therefore, the covert surveillance fulfilled the necessity requirement (case Up-1134/18, para. 18).
The surveillance was also proportionate in the strict sense. The fact that the recording device and the cash trap were placed only in the drawer of the patient’s drawer was relevant. Also, the device only started recording when it detected movement and stopped recording when it no longer detected movement. Therefore, it recorded only those persons who opened the drawer and kept recording them for as long as the drawer was open. It only recorded the area immediately in front of the opened drawer. Moreover, it is also relevant that the covert surveillance cleared other workers – who did not commit workplace violations – of suspicion (case Up-1134/18, para. 19).
Based on all the above, the Constitutional Court held that, in the circumstances of the present case, the gravity of the repeated thefts (infringements) outweighed the consequences of the interference with the right to privacy in the workplace. Consequently, the interference was not excessive, and there was no violation of the right to privacy under Article 35 of the Constitution (case Up-1134/18, para. 20). Consequently, the Constitutional court did not address the question of admissibility of the submitted evidence any further (since there was no violation of worker’s right to privacy).
