Profiling and imaging of forensic evidence – A pan-European forensic round robin study part 1: Document forgery

The forensic scenario, on which the round robin study was based, simulated a suspected intentional manipulation of a real estate rental agreement consisting of a total of three pages. The aims of this study were to (i) establish the amount and reliability of information extractable from a single type of evidence and to (ii) provide suggestions on the most suitable combination of compatible techniques for a multi-modal imaging approach to forgery detection. To address these aims, seventeen laboratories from sixteen countries were invited to answer the following tasks questions: (i) which printing technique was used? (ii) were the three pages printed with the same printer? (iii) were the three pages made from the same paper? (iv) were the three pages originally stapled? (v) were the headings and signatures written with the same ink? and (vi) were headings and signatures of the same age on all pages? The methods used were classified into the following categories: Optical spectroscopy, including multispectral imaging, smartphone mapping, UV-luminescence and LIBS; Infrared spectroscopy, including Raman and FTIR (micro-)spectroscopy; X-ray spectroscopy, including SEM-EDX, PIXE and XPS; Mass spectrometry, including ICPMS, SIMS, MALDI and LDIMS; Electrostatic imaging, as well as non-imaging methods, such as non-multimodal visual inspection, (micro-)spectroscopy, physical testing and thin layer chromatography. The performance of the techniques was evaluated as the proportion of discriminated sample pairs to all possible sample pairs. For the undiscriminated sample pairs, a distinction was made between undecidability and false positive claims. It was found that none of the methods used were able to solve all tasks completely and/or correctly and that certain methods were a priori judged unsuitable by the laboratories for some tasks. Correct results were generally achieved for the discrimination of printer toners, whereas incorrect results in the discrimination of inks. For the discrimination of paper, solid state analytical methods proved to be superior to mass spectrometric methods. None of the participating laboratories deemed addressing ink age feasible. It was concluded that correct forensic statements can only be achieved by the complementary application of different methods and that the classical approach of round robin studies to send standardised subsamples to the participants is not feasible for a true multimodal approach if the techniques are not available at one location.     

Study on the tracking revision history of MS Word files for forensic investigation

Document forensics remains an important field of digital forensics. To date, previously existing methods focused on the last saved version of the document file stored on the PC; however, the drawback of this approach is that this provides no indication as to how the contents have been modified. This paper provides a novel method for document forensics based on tracking the revision history of a Microsoft Word file. The proposed method concentrates on the TMP file created when the author saves the file and the ASD file created periodically by Microsoft Word during editing. A process whereby the revision history lists are generated based on metadata of the Word, TMP, and ASD files is presented. Furthermore, we describe a technique developed to link the revision history lists based on similarity. These outcomes can provide considerable assistance to a forensic investigator trying to establish the extent to which document file contents have been changed and when the file was created, modified, deleted, and copied.     

论行政规定在行政诉讼中的效力

在现行法律体制下,行政规定不属于法律渊源,不是行政诉讼中法院必须适用的法律依据。但行政规定是行政机关作出行政行为的依据,在现实社会中具有重要的规范功能。在行政诉讼中,法院对行政规定既不能完全抛开,又不能完全信任。为了回应社会现实,应当在形式法治的框架内,融入部分实质法治的要素,附条件地承认行政规定的效力,并由法院依照这些条件和规则予以审查。     

“裁判文书网上公开”的三个隐忧

一般认为,裁判文书的公开是司法民主理念的要求,它不仅有利于建立＂阳光司法＂,也能保障公民的知情权与监督权。并且,在互联网时代,裁判文书网上公开成为必然趋势。但是,在当前的社会环境与制度背景下,将裁判文书在网上予以全面公开尚且存在隐忧,主要涉及理念碰撞、司法性质追问、社会实效等具体问题。     

文书写作中模糊语言的使用

在公安文书写作中,不仅需要确定性语言,同样需要运用无法确定其外延的模糊性语言。模糊语言有其特征和不可替代的作用,在公安文书的写作中应根据具体情况,恰当使用模糊语言,使公安文书正确地反映客观事实,发挥其应有的作用。     

Use of lycode powders for the examination of documents partially written with erasable ball point pen inks

It was discovered by change that lycode powders adhere to erasable ball point pen ink strokes. A study of this phenomenon was carried out to determine what type of inks reacts physically with lycode powders. A further evaluation was made to learn if this effect continued after the erasable ink became indelible. It was also found that obliterated erasable ball point pen ink can be read by applying lycode powders and that the powders react in a similar way with typewriting from a conventional inked typewriter ribbon. Treatment in this case is completely non-destructive since the lycode powder can be wiped off the paper surface.     

对交通技术监控违法行为告知制度的思考

由于交通技术监控违法行为的告知制度存在着漏洞,引发了一些比较突出的问题,给具体参与交通活动的当事人造成了误解,甚至对其合法权利造成侵害。因此,我们应进一步完善相关法律制度,在宏观上平衡法律规范之间的适应性和统一性,丰富告知后进行处罚的种类和方式。     

美国证据法视野下的习惯和操作规程证据规则

习惯和操作规程证据规则作为证据法上相关性理论的重要组成部分,在我国并没有得到证据法学界的重视。美国对习惯和操作规程证据的使用已有了相对成熟的规定,我们有必要对其进行研究以吸收其内在合理性因素,以期对我国司法实践产生积极的影响。     

El requerimiento notarial y su contestación como título ejecutivo del crédito: la confesión extrajudicial de la deuda

Requirement out of courtesy can come true for the creditor for legal process or out-of-court. The out-of-court reclamation he must get along well, in principle, like any halfback For the fact that the creditor demand the fulfillment to the debtor of his obligation to be this one defeated, liquid and exigible. He is interesting to the ends of our discourse in this order to pass remarks on the previous paths to claim payment of what they owe to us, doing especial emphasis in the notarial requisite and his plausible and ulterior executive property, in the event the creditor not see satisfied his credit for this form of reclamation and find himself specified to resort to legal action; When to become converted the act of requisite in half probatory term of possible extrajudicial confession of debt, SFA expressed or tacit, susceptible of immediate judicial execution.     

A U.N. Convention to Regulate PMSCs?

Abstract

In the last 20 years the ruthless competition for natural resources, political instability, armed conflicts, and the terrorist attacks of 9/11 have paved the way for private military and security companies (PMSCs) to operate in areas which were until recently the preserve of the state. PMSCs, less regulated than the toy industry, commit grave human rights violations with impunity. The United Nations has elaborated an international binding instrument to regulate their activities but the opposition of the U.S., U.K., and other Western governments—and from PMSCs, which prefer self-regulation—have prevented any advancement.
