Criminal Lawyers in Assault on Authority

The crime of assault on authority (Arts. 550-556 of the Spanish Criminal Code) is one of the most controversial offences under Title XXII on crimes against public order. The protected legal interest is twofold: on the one hand the principle of authority as a pillar of the rule of law, and on the other the physical integrity and freedom of action of the agents and officials exercising public functions. The Supreme Court makes clear that not every friction with an officer falls within the type: an attack endowed with a certain entity and an intentional element of contempt for the public function is required.

The Criminal Code provides a graduated scheme. The core conduct is the assault of Art. 550: attacking, offering serious active resistance or seriously intimidating an authority, an agent or a public official in the exercise of their functions. Art. 556 punishes non-serious resistance and disobedience to authority, with notably lower penalties. Arts. 554 and 555 extend protection to those who come to the aid of officers or to assimilated professionals (healthcare workers, public-school teachers, firefighters, private security personnel cooperating with police).

Penalties are substantial and graduated according to the passive subject and the means used. Basic assault on an authority agent carries 1 to 4 years' imprisonment and 3 to 6 months' fine; against an authority (mayors, judges, MPs), 1 to 6 years' imprisonment and 6 to 12 months' fine. Specific aggravations (Art. 551 CP) apply where weapons or dangerous instruments are used, where a motor vehicle is employed, where there is serious risk to life, or where the attack targets members of the Armed Forces. Non-serious resistance under Art. 556 carries 3 months to 1 year prison or fine, and mild disobedience is an administrative infraction under Organic Law 4/2015 on Citizen Security.

Technical defense rests on several axes consolidated by case-law. The first is requalification to resistance under Art. 556: many police reports describe scuffles, attempts to break free or falls to the ground that hardly reach the "serious entity" required by the Supreme Court. The second axis is the challenge to the presumption of veracity of the police report: constitutional doctrine (STC 35/2006, among many) recalls that the officer's statement is testimonial evidence subject to contradiction, not conclusive truth, and may be contrasted with bodycams, municipal cameras, witness videos and reciprocal injury reports. The third axis is self-defense against police excess: when the officer acts outside the legal framework or uses disproportionate force, the citizen may repel the aggression under Art. 20.4 CP, a restrictive doctrine but applied by the Supreme Court in extreme cases. Finally, the intoxication mitigating factor (Art. 21.2) or outburst (Art. 21.3) may apply where serious affectation of will is proven.

In forensic practice, assault proceedings have multiplied in the context of nightlife, demonstrations, traffic controls and, in recent years, healthcare and educational conflicts. Organic Law 14/2022 and the public-order reform have toughened the criminal response, especially where injuries occur, vehicles are used or attacks target police units in public order. At Alonso Sala we intervene from legal assistance at the police station, the critical moment when the investigated party's initial version is documented and urgent measures are requested (seizure of bodycams, requests for recordings from nearby premises, certification of images from the Coordination Centre). Our strategy combines technical-procedural defense with private medical experts who challenge the mechanics of the injuries claimed by officers, and the active search for independent witnesses that break the one-sided logic of the police report. We approach each case with the conviction that constitutional guarantees must prevail over accusatory inertia.
