Digital Wiretap Warrant: Improving the security of ETSI Lawful Interception

Lawful Interception (LI) of data communications is an essential tool for Law Enforcement Agencies (LEA) in order to investigate criminal activities carried out or coordinated by means of Internet. However, the ability to secretly monitor the activities of citizens also has a great impact on civil rights. Therefore, democratic societies must prevent abuse and ensure that LI is only employed in specific cases with justifiable grounds or a probable cause. Nowadays, in many countries each interception must be authorized by a wiretap warrant, usually issued by a judge. However, this wiretap warrant is merely an administrative document that should be checked by the network or service operator before enabling the monitoring of its customers, whose communications are later handed over to a LEA in plaintext. This paper proposes the idea of employing a Digital Wiretap Warrant (DWW), which further protects the civil liberties, security and privacy of LI by ensuring that monitoring devices can only be enabled with a valid DWW, and by encrypting the captured data so only the authorized LEA is able to decrypt those communications. Moreover, in the proposed DWW framework all digital evidence is securely time-stamped and signed, thus guaranteeing that it has not been tampered with, and that a proper chain of custody has been met. In particular this paper proposes how to apply the DWW concept to the lawful interception framework defined by the ETSI LI Technical Committee, and evaluates how the additional security mechanisms could impact the performance and storage costs of a LI platform.     

自白任意性规则的法律价值

新刑事诉讼法和此前“两高三部”发布的有关刑事证据的规定，确立了非法证据排除规则，但这一进步却因模糊了对威胁、引诱和欺骗取得口供的排除态度而显得 不彻底。自白任意性被忽视，主要归因于过分倚重口供的司法惯性，作为自白任意性法理基础的正当程序观念没有得到普遍认同，对秩序的偏重则是更为深层的原因。自白的证据能力若不以自白的任意性为条件，冤错案件的病灶就不能祛除，司法实践就不可能取得实质的进步。认同自白任意性规则的法律价值，不仅能为发现案件真实提供保障，更是保障刑事司法最终摆脱纠问式特征之所必需。     

检察环节证据合法性审查实证研究

修订后的《刑事诉讼法》规定了检察机关的非法证据排除义务,并对检察环节开展证据合法性审查的具体程序和相应职责予以了明确规定。从司法实践来看,侦查活动的密闭性、审查模式的单一性、立法的不完善以及在审查过程中自由裁量缺乏必要的规制等问题制约了证据合法性审查的实效。为此,有必要从审查程序、配套制度以及认证规则等方面予以完善。     

论刑事诉讼中的同案犯证言

在刑事诉讼活动中,提供证言的同案犯具有特殊地位。在刑事侦查工作中,同案犯证言发挥了十分关键的作用,也引发了一系列证据法和程序法问题。同案犯证言具有潜在的不可靠性,可通过健全证据开示制度及法官审查制度等措施保证该证据的正确适用。     

讯问同步录音录像制度新探

2006年1月,最高人民检察院决定,今后各级检察机关在办理贿赂和其他职务犯罪要案中要逐渐实行讯问同步录音录像制度。公安机关在办理大案、要案中也已经实施讯问的同步录音录像制度。但在实践中,由于缺乏统一的规范和格式,各地在操作中不免出现一些问题,如在录像中看不到被讯问人的正面,更看不清其表情神态;在录像中只完整显示一名承办人,另一名则仅有半个身体;在录像中没有时间显示;声音不够清晰等等。因此,有必要建立规范的讯问同步录音录像制度。     

补强证据规则--兼论口供的证据价值

补强证据规则是对诉讼过程中的采证、认证经验的总结,其在程序上对证据的证明力予以直接限制,体现了对法官认证的自由裁量权的规范和控制。我国目前还没有确立补强证据规则,理论上也缺乏对补强证据规则的系统研究。但司法实践中会经常运用到补强证据及其规则。     

电子证据带给行政执法工作的挑战与对策

电子证据作为一种崭新的证据种类已经在执法实践中发挥了比较大的作用。但由于现行法律还没有对电子证据给予明确的规定,因此,有关电子证据的概念问题、其法律地位的界定问题、其法律价值的评价问题等应是电子证据研究的首要问题。此外,研究电子证据可以对具体的行政执法工作提供有益的帮助。     

台湾地区民事证据保全制度改革及其借鉴意义

为了彻底改造所移植外国法,更新传统诉讼观念,解决诉讼拖延、效率低下和诉讼成本高昂问题,我国台湾地区于20世纪末、21世纪初就证据保全制度从立法理念到具体内容进行了重大变革。新证据保全制度所蕴含的保障程序主体权、扩大诉讼解决纠纷能力、疏减讼源及预防纠纷发生的理念,以及为贯彻该等理念在设置具体制度时,扩大证据保全范围、规定并引导当事人于证据保全程序中达成协议和严格证据保全的程序保障的做法,对大陆证据保全制度的改革具有借鉴作用。

Parental Alienation in U.S. Courts, 1985 to 2018

Courts have been dealing with alienating behaviors in high conflict family litigation for hundreds of years. Experts in the behavioral sciences have been writing about mothers and fathers manipulating their children to disparage the other parent for more than seventy years. But in the last two decades some social scientists and legal professionals have questioned the legitimacy of parental alienation as a concept and its admissibility in child abuse and child custody litigation. This study was designed to examine the extent to which courts in the United States have found the concept of parental alienation material, probative, relevant and admissible. Thirty‐four years of cases were found with a WESTLAW query and analyzed. Cases were selected for study only if the record reflected that a judge or an independent expert found the concept of parental alienation to be of value in the litigation. Results illustrate increasing awareness of the concept and document its admissibility in every one of the United States. The numbers, sex of the alienating parent and prevalence of significant custody changes are discussed. Limitations inherent in this form of quantitative analysis are also discussed with recommendations for future research.
