In contrast to open measures, information is gathered <strong>covertly and often over a longer period<\/strong> to avoid distorting real events. <\/p>\n\n<p class=\"wp-block-paragraph\">The legal basis for the definition of terms is found in the Code of Criminal Procedure (StPO). It clearly defines what is to be understood by the individual measures. <\/p>\n\n<p class=\"wp-block-paragraph\">According to the legal definition <strong>pursuant to <a href=\"https:\/\/ris.bka.gv.at\/eli\/bgbl\/1975\/631\/P129\/NOR40050588\" target=\"_blank\" rel=\"noreferrer noopener\">\u00a7 129 StPO<\/a><\/strong>:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Surveillance<\/strong> is the <strong>secret monitoring of a person&#8217;s behavior<\/strong><\/li>\n\n\n\n<li><strong>Undercover investigation<\/strong> is the <strong>use of criminal police officers or commissioned persons<\/strong> who <strong>do not disclose their official position or mission<\/strong><\/li>\n\n\n\n<li><strong>Sting operation<\/strong> is the <strong>attempted or apparent execution of criminal acts<\/strong>, particularly in connection with <strong>illegal items or assets or those originating from crimes<\/strong><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">These definitions are legally binding and form the basis for all further requirements and limits of the measures.<\/p>\n\n<p class=\"wp-block-paragraph\">In practical classification, a clear graduation is evident: while surveillance represents a comparatively restrained form of information gathering, undercover investigations and especially sting operations interfere significantly more intensively with the rights of those affected.<\/p>\n\n<p class=\"wp-block-paragraph\">For this reason, the precise conceptual distinction is not merely theoretical. It determines <strong>which requirements must be met, who may order the measure, and how long it may be carried out<\/strong>. <\/p>\n    <div class=\"mr-quote mrbg clearfix\">\n        <a class=\"mr-quote-person\" href=\"\/ueber-uns\/rechtsanwalt-peter-harlander\/\" title=\"Rechtsanwalt Peter Harlander\">\n            <img decoding=\"async\" class=\"mr-quote-person-img\" src=\"https:\/\/harlander-partner.eu\/wp-content\/themes\/harlander\/design\/ph100.webp\" width=\"100\"\n                 height=\"100\" loading=\"lazy\" alt=\"Rechtsanwalt Peter Harlander\">\n            <span class=\"mr-quote-person-text\">\n            Peter Harlander<br>\n            <span class=\"mr-quote-person-function\">Harlander &amp; Partner Rechtsanw\u00e4lte<\/span>\n        <\/span>\n        <\/a>\n        <span class=\"mr-quote-content\">\u201eParticularly with undercover investigative measures, the importance of precise legal classification is evident, as the conceptual distinction alone determines requirements, jurisdiction, and defense approaches.\u201c<\/span>\n    <\/div>\n<a class=\"mr-cta-link mr-cta-button-cal\" href=\"#h2-booking\" title=\"Free initial consultation\"><span class=\"mr-cta-link-normal\">Select your preferred appointment now:<\/span><span class=\"mr-cta-link-bold\">Free initial consultation<\/span><\/a>\n\n<h2 class=\"wp-block-heading\" id=\"h-voraussetzungen-der-observation-im-strafverfahren\">Requirements for Surveillance in Criminal Proceedings<\/h2>\n\n<p class=\"wp-block-paragraph\">Surveillance is permissible if it appears necessary for the <strong>investigation of a crime<\/strong> or for <strong>determining the whereabouts of an accused person<\/strong>, pursuant to <a href=\"https:\/\/www.ris.bka.gv.at\/eli\/bgbl\/1975\/631\/P130\/NOR40050589\" target=\"_blank\" rel=\"noreferrer noopener\">\u00a7 130 StPO<\/a>. A <strong>specific investigative purpose<\/strong> is therefore decisive; mere suspicions are not sufficient. <\/p>\n\n<p class=\"wp-block-paragraph\">In its basic form, the criminal police can carry out surveillance independently. However, the legal requirements increase as soon as the measure becomes more intensive. This applies in particular to longer surveillance or those with increased intensity of intervention.  <\/p>\n\n<p class=\"wp-block-paragraph\">The central question is always that of <strong>necessity<\/strong>.

The <strong>opening of vehicles or containers<\/strong> to attach such devices is also permitted, but only under narrow conditions. <\/p>\n\n<p class=\"wp-block-paragraph\">The prerequisite is that surveillance would be <strong>futile or significantly more difficult<\/strong> without this support.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-dauer-und-besondere-formen-der-observation\">Duration and Special Forms of Surveillance<\/h3>\n\n<p class=\"wp-block-paragraph\">As soon as surveillance <strong>exceeds a period of more than 48 hours<\/strong>, is carried out abroad, or is supported by technical means, stricter requirements apply, pursuant to <a href=\"https:\/\/www.ris.bka.gv.at\/eli\/bgbl\/1975\/631\/P130\/NOR40050589\" target=\"_blank\" rel=\"noreferrer noopener\">\u00a7 130 para. 3 StPO.<\/a><\/p>\n\n<p class=\"wp-block-paragraph\">In these cases, there must be a <strong>specific suspicion of an intentional crime<\/strong> punishable by more than one year of imprisonment.

For long-term and systematic operations, the legal requirements increase significantly. In such cases, there must regularly be an intentional crime punishable by more than one year of imprisonment, and the investigation would otherwise be significantly more difficult. Furthermore, the operation and results must be continuously documented and monitored.   <\/p><\/div><\/div><div class=\"wp-block-uagb-faq-child uagb-faq-child__outer-wrap uagb-faq-item uagb-block-OBSERVATION-VERDECKTE-ERMITTLUNG-SCHEINGESCHAEFT-Q4 \" role=\"tab\" tabindex=\"0\"><div class=\"uagb-faq-questions-button uagb-faq-questions\">\t\t\t<span class=\"uagb-icon uagb-faq-icon-wrap\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 448 512\"><path d=\"M432 256c0 17.69-14.33 32.01-32 32.01H256v144c0 17.69-14.33 31.99-32 31.99s-32-14.3-32-31.99v-144H48c-17.67 0-32-14.32-32-32.01s14.33-31.99 32-31.99H192v-144c0-17.69 14.33-32.01 32-32.01s32 14.32 32 32.01v144h144C417.7 224 432 238.3 432 256z\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t<span class=\"uagb-icon-active uagb-faq-icon-wrap\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 448 512\"><path d=\"M400 288h-352c-17.69 0-32-14.32-32-32.01s14.31-31.99 32-31.99h352c17.69 0 32 14.3 32 31.99S417.7 288 400 288z\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/span>\n\t\t\t<span class=\"uagb-question\">What is a sting operation in criminal proceedings?<\/span><\/div><div class=\"uagb-faq-content\"><p>A sting operation is the apparent execution or preparation of a criminal act to convict perpetrators or secure assets.

A sting operation is only permissible if the investigation of a felony or the seizure of relevant assets would otherwise be significantly more difficult. However, it remains impermissible to induce someone to commit a crime through state conduct.   <\/p><\/div><\/div><div class=\"wp-block-uagb-faq-child uagb-faq-child__outer-wrap uagb-faq-item uagb-block-OBSERVATION-VERDECKTE-ERMITTLUNG-SCHEINGESCHAEFT-Q5 \" role=\"tab\" tabindex=\"0\"><div class=\"uagb-faq-questions-button uagb-faq-questions\">\t\t\t<span class=\"uagb-icon uagb-faq-icon-wrap\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 448 512\"><path d=\"M432 256c0 17.69-14.33 32.01-32 32.01H256v144c0 17.69-14.33 31.99-32 31.99s-32-14.3-32-31.99v-144H48c-17.67 0-32-14.32-32-32.01s14.33-31.99 32-31.99H192v-144c0-17.69 14.33-32.01 32-32.01s32 14.32 32 32.01v144h144C417.7 224 432 238.3 432 256z\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t<span class=\"uagb-icon-active uagb-faq-icon-wrap\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewBox= \"0 0 448 512\"><path d=\"M400 288h-352c-17.69 0-32-14.32-32-32.01s14.31-31.99 32-31.99h352c17.69 0 32 14.3 32 31.99S417.7 288 400 288z\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/span>\n\t\t\t<span class=\"uagb-question\">Why is legal support particularly important for undercover investigative measures?<\/span><\/div><div class=\"uagb-faq-content\"><p>Undercover investigative measures interfere deeply with the rights of those affected and are therefore subject to narrow legal limits. Even minor errors in ordering, duration, execution, or documentation can have significant consequences for the proceedings. A legal review shows early on whether evidence was obtained lawfully and whether specific points of attack arise. This is precisely why legal support is useful if you want to check the lawfulness of the measure and strengthen your defense position.   <\/p><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"In criminal proceedings, surveillance, undercover investigation, and sting operations provide three graduated forms of undercover investigative measures, each with different levels of intrusive depth.
