A biological sample collection ordered by the authority can raise immediate doubts: is it truly mandatory, which act authorizes it, must counsel be notified, and what happens if the sample is acquired using methods other than those indicated? The issue concerns personal liberty and, precisely for this reason, the code of criminal procedure does not allow generic measures or techniques without limits.
I will explain which differences matter to understand if and how to challenge the act. The first is decisive: a sample collection to identify a person does not necessarily follow the same rules as an expert examination ordered by the judge or an urgent intervention by the public prosecutor. We will see what must appear in the measure, which limits protect health and dignity, and which facts make a challenge concrete.
First of all: which sample collection has been ordered?
The purpose of the act determines the applicable rules. The term “biological sample collection” can indicate the collection of hair, body hair, saliva, or oral mucosa for DNA, but also a medical assessment. Therefore, looking at the type of sample is not enough: one must understand whether the authority wants to identify a person, carry out an expert examination in the proceedings, or quickly acquire an element useful for the investigations.
Specific rules exist for identification. Article 349, paragraph 2-bis, of the code of criminal procedure concerns the compulsory collection of hair or saliva from a person under investigation when consent is lacking. In this case, the judicial police must have authorization from the public prosecutor, either in writing or orally and then confirmed in writing, and must respect personal dignity. The text of the provision introduced for this hypothesis can be consulted in the Normattiva reference on sample collection for identification.
Expert examination and urgency instead follow articles 224-bis and 359-bis. Here it is not merely a matter of recognizing a person: the act aims to form or acquire evidence in the proceedings. The law requires, depending on the situation, an order from the judge or a reasoned decree from the public prosecutor subject to validation. Confusing these paths risks causing the challenge to focus on the wrong rule.
Compulsory sample collection ordered by the judge
Consent remains the starting point. If consent is lacking and the execution of an expert examination requires an act capable of affecting personal liberty, the judge may order compulsory execution only under the conditions provided by article 224-bis c.p.p. The rule concerns non-culpable offenses, whether consummated or attempted, punished with life imprisonment or maximum imprisonment exceeding three years, in addition to cases expressly indicated by the law and the offenses of vehicular homicide and vehicular personal injury.
The act must be absolutely indispensable for the evidence. It is not sufficient that the sample collection is useful or potentially convenient for the investigation. The order must explain why that specific examination is necessary to prove the facts and must specifically indicate which sample collection or assessment will be carried out. An indistinct reference to biological examinations does not allow understanding which intervention has been authorized nor whether the chosen methods correspond to the measure.
The order must contain essential data under penalty of nullity. It must identify the interested person, indicate the offense, and summarily describe the fact. It must also specify the sample collection or assessment, the reasons for indispensability, the right to be assisted by counsel or a trusted person, the consequences of failing to appear without a legitimate impediment, and the place, day, hour, and methods of the operation.
Ordinary notification precedes the operation by at least three days. Article 224-bis provides that the order be notified to the interested person, the defendant, and their counsel, as well as the victim, with this advance notice relative to the expert operations. The same rule also establishes the nullity of the act if the person subjected to the sample collection or assessment is not assisted by the appointed counsel. The discipline is reported in the Normattiva text of articles 224-bis and 359-bis c.p.p..
Health, dignity, and less invasive technique
Not every physically possible intervention is permitted. Article 224-bis prohibits operations in contrast with express prohibitions of the law, which are dangerous to the life, physical integrity, or health of the person or the unborn child. It also excludes those that, according to medical science, can cause suffering of a non-minor entity. These limits concern the concrete sample collection, not merely its formal authorization.
The less invasive technique must be chosen when it offers the same result. An oral swab, a blood sample, or a different assessment are not interchangeable by definition. The useful question is whether a less invasive method was effectively capable of achieving the same evidentiary result. It is not enough to prefer a less unwelcome solution: the alternative must be suitable for the same investigative purpose.
Physical coercion also has a limit. If the person does not appear without putting forward a legitimate impediment, the judge may order compulsory accompaniment. If they appear but refuse consent to a legitimately ordered assessment, compulsory execution may be ordered. However, means of physical coercion are permitted only for the time strictly necessary for execution, without eliminating the limits of health, dignity, and modesty established by the law.
When the public prosecutor intervenes due to urgency
Urgency does not coincide with the simple need to act quickly. Ordinarily, when consent is lacking, the public prosecutor requests authorization for operations from the judge for preliminary investigations. Article 359-bis c.p.p. allows the public prosecutor to order them directly only when there is a grounded reason to believe that delay could cause serious or irreparable prejudice to the investigations.
The urgent decree must be reasoned and specific. It must contain the same elements required for the judge's order by article 224-bis, including the indication of the sample collection or assessment and the envisaged methods. Saying that a sample might become more difficult to acquire does not replace the motivation required by the law: urgency must be linked to the facts and to the concrete risk deriving from delay.
Judge validation follows close timeframes. The public prosecutor must request validation of the decree and of any compulsory accompaniment within the subsequent forty-eight hours. The judge rules as soon as possible and in any case within the subsequent forty-eight hours. The temporal sequence must be read together with the content of the act: compliance with the timeframe does not render a decree that omits essential elements irrelevant.
For these operations, the law links precise defects to precise consequences. Article 359-bis recalls, under penalty of nullity of the operations and unusability of the acquired information, the prescriptions on the content of the measure and on health and lesser invasiveness limits. In proceedings for vehicular homicide or vehicular personal injury, a particular urgent discipline also exists, which in certain cases allows oral measures later confirmed in writing and provides prompt notice to counsel, who may assist without delaying the operation.
How the method of sample collection is truly challenged
An effective challenge links a fact to a violated guarantee. It is not sufficient to say that the sample or its outcome are unfavorable. The point may be, instead, the absence of a specific indication of the technique, insufficient reasoning on indispensability, failure to comply with ordinary notice, lack of counsel assistance in the case governed by article 224-bis, or an urgent decree lacking the required requirements.
Measure and report answer different questions. The order or decree show who ordered the act, for what reason, and with what limits. The report of the operations instead documents what took place: date, place, persons present, acquired sample, and execution methods. If the report describes an activity that is more invasive or different from that authorized, the comparison between the two documents becomes central.
An irregularity does not always produce the same effect. The code expressly provides for nullity or unusability for certain violations, while other defects require a different classification. For this reason, it is important not to overlap the vice of the measure, the manner in which the act was executed, and the problem of the subsequent use of the result. These are connected issues, but not identical.
The stage of the proceeding affects the manner of raising the issue. There is no universal formula that applies before the operation, during the act, and at trial. If you receive a notice, a decree, or an order, keeping a copy of it together with the report and relevant medical documentation helps distinguish concrete doubt from a merely generic challenge.
Choices to consider without confusing refusal and defense
A real impediment must be presented in a verifiable manner. Ignoring the summons does not equate to challenging the act. The law treats failure to appear without a legitimate impediment differently, as it can lead to compulsory accompaniment. If a health condition truly prevents presenting oneself or undergoing the assessment, the fact must be documented in a manner consistent with the scheduled act and the deduced health risk.
Refusal does not replace legality control. Before a measure that falls within the conditions of the law, the refusal of the person present can lead to compulsory execution. The distinct issue is whether the authority has indicated and respected all the envisaged prerequisites. Accurately identifying the defect allows addressing the problem without confusing the expression of dissent with the validity of the act.
The first practical point is reconstructing the perimeter of the operation. Date of the notice, authority that ordered the sample collection, indicated reason, type of sample, presence of counsel, report, and health conditions are elements that can change the answer. I can help you read these acts by distinguishing the challenge to the methods from a generic protest against the sample collection.
Frequently asked questions
Can I refuse a biological sample collection ordered by the judge?
You can express refusal, but you do not always prevent the operation. If the prerequisites of article 224-bis are met and the judge has ordered compulsory execution, the refusal of the person who appears can lead to the execution of the assessment. The power to execute the act and the control over the content of the order, defense, health, and technique employed remain distinct.
Must counsel assist during the sample collection?
In compulsory expert examination ordered by the judge, assistance is essential. Article 224-bis establishes the nullity of the act if the person subjected to the sample collection or assessments is not assisted by the appointed counsel. In urgent hypotheses of the public prosecutor, the applicable discipline must be distinguished; for the special vehicular procedure, the law provides prompt notice to counsel and their right to assist.
Do the three days of advance notice always apply?
No, the timeframe concerns ordinary expert procedure. The judge's order provided by article 224-bis must be notified at least three days before the operations. In urgent cases governed by article 359-bis, the law allows the public prosecutor's reasoned decree precisely because delay can cause serious or irreparable prejudice to the investigations.
Can a sample collection that is more invasive than necessary be challenged?
Yes, if an equivalent less invasive alternative exists. The law prohibits operations dangerous to life, physical integrity, or health, and those capable of causing suffering of a non-minor entity according to medical science. It also requires choosing the less invasive technique given equal results: the alternative must therefore be concretely suitable for the same assessment.
If the act is null, is the sample automatically eliminated?
Nullity and material fate of the sample are different issues. Nullity concerns the validity of the procedural operation; article 359-bis also links specific violations to the unusability of the acquired information. The management of the sample, analytical results, and any preserved data depends on the applicable discipline and the measures adopted in the individual proceeding.
Regulatory references
The main framework is in the code of criminal procedure. Articles 224-bis and 359-bis govern, respectively, expert examination with acts affecting personal liberty and compulsory collection of biological samples from living persons ordered by the public prosecutor. For the different case of sample collection aimed at identification, article 349, paragraph 2-bis, is relevant.
