Criminal Lawyers in Illegal Detention by Private Individuals

Illegal detention by private individuals typified in Art. 163 CP sanctions the individual who confines or detains another, depriving them of their liberty without legal justification. The protected legal interest is the ambulatory liberty of the victim, recognised as fundamental right in Art. 17 of the Spanish Constitution as manifestation of the right to personal freedom. The typical conduct demands three elements: a positive or omissive action of confinement or detention (effective deprivation of freedom of movement), the absence of legal cause justifying the deprivation, and direct or eventual intent of the active subject. Consolidated Supreme Court case-law has clarified that any effective restriction of ambulatory liberty, whether by physical confinement or equivalent intimidation, integrates the offence, without minimum duration or specific harmful result being required.

The methods of commission are extraordinarily diverse. Physical confinement through door closures, exit blocking, restraint through ties or use of locks is the classic modality. Detention by intimidation employs threats, exhibition of weapons or dangerous objects, or psychological pressure effectively preventing the victim from leaving the place. Abusive labour retention integrates cases where an employer prevents the worker's exit by retention of documentation or by physical means. Retention in a moving vehicle without allowing the passenger to descend. Deprivations of liberty in family contexts, including the confinement of spouses, partners or elderly ascendants, integrate especially serious specific modalities when gender or domestic violence concurs. The retention of minors by non-parent third parties configures qualified modalities. The aggravated modalities of Art. 163 CP include detentions exceeding 15 days (5 to 8 years' penalty) and simulation of authority or public function.

The penalties are graduated according to the entity of the wrong. The basic offence of Art. 163.1 CP carries 4 to 6 years prison. The attenuated modality of Art. 163.2 provides for the imposition of a penalty lower by one degree (2 to 4 years prison) when the culprit gives liberty to the confined or detained person within the first 3 days without having achieved the intended object. The aggravated modality of Art. 163.3 punishes with 5 to 8 years prison when the detention lasts more than 15 days, or authority or public function is simulated (Art. 165 CP), or executed against minor or vulnerable person. The qualified forced disappearance of Arts. 166-168 CP, when subsequent concealment concurs, carries penalties of 10 to 15 years. To custodial penalties are added accessory consequences: absolute disqualification during service, criminal record with relevant effects, and civil liability ex delicto for moral damages, loss of earnings and, where appropriate, psychological expenses derived from the trauma suffered.

The technical defense in illegal detention by private individuals is built on four axes consolidated by case-law. First, the concurrence of flagrant offence: Art. 490 LECrim authorises any person to detain whoever attempts to commit a crime, the offender in flagrante or the escaped, having to immediately place the detainee at the disposal of the authority; action within this framework excludes typicity. Second, the brevity and proportionality of the retention: when the duration is very brief (minutes) and proportional to a legitimate purpose (preservation of evidence, waiting for the police), it may not reach the entity necessary for consummation. Third, the consent of the alleged victim: when the person remained voluntarily without effective opposition, no criminally relevant deprivation of liberty concurs. Fourth, the voluntary release within 3 days of Art. 163.2 CP, which substantially reduces the penalty. The general defences (state of necessity, insurmountable fear) may apply in exceptional contexts.

In current forensic practice, illegal detention proceedings by private individuals concentrate on four typical scenarios: retentions in partner or ex-partner contexts (especially in gender violence), abusive labour retentions (including cases linked to human trafficking with documentation withdrawal), retentions of employees during robberies or thefts at establishments, and deprivations of liberty in conflictive family contexts (especially between siblings for inheritance conflicts or between separated parents for child abduction). Organic Law 1/2025 on Justice Service Efficiency, Organic Law 1/2004 on gender violence (when jurisdiction of the Court of Violence against Women applies), and consolidated Supreme Court case-law configure the normative framework. At Alonso Sala, with 15+ years' experience, we undertake specialised technical defence of the accused individual articulating rigorous analysis of the concurrence of justification causes (flagrant offence, legitimate exercise of right), technical expert evidence when necessary, mitigation for early voluntary release, and, where appropriate, representation of the victim as private prosecution in proceedings against the aggressor with full claim of moral and material damages.
