Electronic monitoring (SDE)

What is electronic monitoring (SDE)?

Electronic monitoring – in Poland commonly referred to as SDE, short for the electronic supervision system – is a form of executing certain criminal-law obligations or measures under technical and legal supervision. In practice, it often allows the convicted person to remain at a designated place of stay, most often their home, while compliance with court-imposed conditions is verified electronically. This solution is used in criminal enforcement proceedings and is not available automatically – it requires a legal basis and a formal decision of the competent court.

Electronic monitoring is most often associated with serving a custodial sentence outside prison, but the system may also be used in other situations provided for by law. Its purpose is to combine punishment or preventive measures with effective control, while reducing the negative consequences of isolation where full imprisonment is not necessary to achieve the objectives of the sentence or measure. From the perspective of the convicted person and their family, SDE may make it possible to continue work, maintain family ties and fulfil everyday responsibilities. From the perspective of the justice system, it is a controlled alternative to detention in a penitentiary unit in cases provided for by law.

Electronic monitoring does not mean full freedom. A person covered by SDE must comply strictly with the schedule and limitations set by the court, including remaining at a specified location at designated times, receiving visits from supervising entities and following technical rules related to the monitoring equipment. A breach of these obligations may lead to the revocation of permission to serve the sentence or comply with the obligation in this form and, as a consequence, to further legal consequences, including imprisonment where applicable.

How does electronic monitoring work in practice?

In practical terms, SDE is based on technical devices that make it possible to verify whether the supervised person complies with the conditions set by the court. Depending on the legal basis and the type of supervision, the system may involve checking presence at a specified place or monitoring movement and compliance with restrictions. The technical model used in a given case depends on the content of the judicial decision and the statutory framework.

Before electronic monitoring is implemented, the court examines whether the statutory conditions are met and whether the measure can be carried out in the specific circumstances. This usually includes assessment of the legal basis, the conduct and circumstances of the person concerned, their place of residence, and the technical feasibility of installing the equipment. The consent of adult co-residents may also be relevant where required for practical implementation of supervision at the chosen address.

Once permission is granted, the supervised person must follow the rules set in the decision with precision. This may include staying at home during specified hours, leaving only for work, medical visits, religious practice or essential daily matters, and immediately informing the relevant authorities about circumstances affecting supervision. SDE is therefore a regulated legal form of supervision, not an informal reduction of punishment.

When can legal assistance be important in SDE cases?

Legal assistance may be important both before an application for electronic monitoring is filed and after supervision has started. In many cases, the key issue is whether the statutory prerequisites are actually met and how to present the facts and evidence in a way that corresponds to the court’s assessment criteria. A properly prepared application may affect not only the speed of the proceedings but also the substantive outcome.

For private individuals, legal support may be needed when a custodial sentence is to be enforced, when a family member is already in prison and may qualify for SDE, or when there are doubts about the conditions of supervision, place of residence or permissible absences. For entrepreneurs and professionals, the issue may also be relevant if serving a sentence or complying with another obligation in the SDE system would allow continued work, management duties or protection of an ongoing business relationship, provided this remains consistent with the court’s restrictions.

Legal support may also be necessary where problems arise during the execution of SDE – for example, an alleged breach of obligations, disputes over the permitted schedule, changes in place of residence, health issues, employment changes or the risk of revocation of the court’s permission. In such situations, both procedural timing and the quality of the explanations submitted to the court may be decisive.

An early consultation with a lawyer can help identify whether electronic monitoring is legally available in a specific case, what documents should be gathered and what risks need to be addressed in advance. It may also reduce the risk of formal errors, unsuccessful applications, breaches of supervision conditions, revocation of permission, or avoidable financial and personal consequences for the person concerned and their family.
