An evaluation of the forensic accountant's role in criminal law proceedings / by J. Slot.Slot, Janneke January 2013 (has links)
Forensic accountants are occasionally called upon to assist in criminal law proceedings. The role of the forensic accountant in such proceedings is usually determined during the engagement of the forensic investigation to assist in the matter under investigation. During such investigations, various investigation techniques may be utilised by the forensic accountant in order to convey the facts and findings of the forensic investigation in a written report, drafted by the forensic accountant. When criminal prosecutions are instituted and the forensic accountant is called upon to act as an expert witness, such evidence is mostly based on the findings of the written report. Thus, in giving evidence, the forensic accountant must ensure that the testimony and evidence will be admissible in court and that the forensic accountant is found to be a credible witness.
Although there are various legal standards that the forensic accountant must adhere to, the ICFP, which is the South African regulatory body for commercial forensic practitioners, is still in its infancy and has as yet not set any standards with which forensic accountants must comply with when assisting in criminal investigations or drafting written reports.
The objective of this study is to highlight the role of the forensic accountant in criminal law proceedings. This objective is reached by clarification of the following:
• the difference between a forensic accountant and an auditor;
• the techniques available to the forensic accountant when conducting a forensic investigation;
• the standards with which a forensic accountant‘s report should comply; and
• the forensic accountant‘s role in testimony.
The study illustrates the difference between a forensic accountant and an auditor and suggests a definition for a forensic accountant. The study furthermore explores various techniques that the forensic accountant may utilise during the investigation. The study also analyses the legal standards with which a forensic accountant must comply in order to ensure the admissibility of the written report and its findings. In order to achieve this, international regulatory standards applicable to forensic accountants are analysed and discussed. Finally, the role of the forensic accountant in court proceedings is examined.
The illustrations in this study will be helpful in determining standards that could be implemented in South Africa to guide forensic accountants in their role in criminal law proceedings. / Thesis (MCom (Forensic accountancy))--North-West University, Potchefstroom Campus, 2013.

Análise da qualidade e da contribuição dos laudos periciais toxicológicos no processo de investigação criminal e sentença judicial em casos envolvendo substâncias ilícitas / Analysis of the quality and contribution of forensic toxicology reports in the process of criminal investigation and court decision in cases involving illegal substancesYoshida, Ricardo Luís 04 March 2015 (has links)
Atualmente, no meio jurídico, há um reconhecimento implícito de que as provas materiais necessitam de embasamento científico para alcançar a autenticidade imprescindível ao estabelecimento da convicção dos magistrados. A natureza de determinados exames, como a classificação de substâncias proibidas, demandam a utilização de técnicas e saberes oriundos das ciências naturais e tecnológicas. O trabalho pericial deve ser pautado pela cientificidade, com a aplicação de conhecimentos de diversas áreas, dentre as quais está incluída a estatística forense. Neste trabalho foram utilizadas ferramentas estatísticas para avaliar a qualidade e a contribuição dos laudos periciais para os casos envolvendo substâncias ilícitas e correlacionar o conteúdo destes documentos com a sentença judicial. Numa primeira etapa foram analisadas as informações contidas em laudos toxicológicos de drogas, com o intuito de quantificar a qualidade e importância que eles poderiam fornecer em um processo. Para isso foram analisados 1008 documentos oficiais de diversas jurisdições, divididos em 504 conjuntos de laudos preliminares e definitivos do mesmo caso forense A intenção foi apreciar um conjunto heterogêneo de documentos para possibilitar uma melhor análise. A quantificação foi apreciada através de equações empíricas elaboradas. A validação do método ocorreu por análise de dados multivariados. A metodologia empregada demonstrou-se bastante robusta. A segunda fase do trabalho foi aplicar o resultado dos exames da etapa precedente e correlacionar com a decisão judicial. Para tanto, foram esmiuçadas 167 sentenças proferidas em primeira instância e que continham os laudos elencados na primeira fase. A ferramenta utilizada foi a inferência Bayesiana. Os resultados apontaram que os laudos periciais sempre foram essenciais neste tipo de procedimento julgatório. A qualidade dos documentos produzidos encontrava-se entre boa e ótima, avalizada pelo parâmetro \"relevância do laudo\". Alguns aspectos nos documentos poderiam ser aperfeiçoados, como, por exemplo, a inserção de fotografias do material apreendido e/ou imagens alusivas às análises laboratoriais. Estes estudos permitiram estabelecer um valor de corte para a quantificação da qualidade dos laudos, a partir do qual houve 100% de concordância entre o laudo direcionado e a sentença, para casos de condenação onde o suspeito foi considerado traficante. Por fim, a metodologia proposta apresentou potencial promissor e possibilidade de ser utilizada em outros tipos de casos forenses, como, por exemplo, homicídios, suicídios e outros. / There is an implicit recognition in the current legal scenario that material evidences require scientific support in order to achieve the authenticity that the magistrates need for making decisions. The nature of certain exams, such as classification of prohibited substances, requires the use of techniques and knowledge from natural sciences and technology. The forensic work must rely on scientific methods and apply knowledge from several areas, including forensic statistics. The present work used statistic tools to evaluate the quality and the contribution of forensic reports about illegal substances; the goal is to correlate the content of these documents with the court ruling. In the first part we analyzed the information from toxicology reports on drugs, aiming at the quantification of the importance they might bear to court proceedings. We have parsed 1008 official documents from several jurisdictions, divided into 504 sets of preliminary and final reports from the same case. The objective was to evaluate a heterogeneous document set for a better analysis. The quantification was determined from elaborate empiric equations. The validation of the method was performed by multivariate data analysis. The methodology used in the present work has proved very robust. The second part was the application of the results from the previous part and correlation to the court ruling. We have thoroughly examined 167 rulings at first instance that contained the reports cited in the first part. We have used Bayesian inference, and the results indicated that forensic reports were always required in this type of court proceeding. The quality of the documents was considered good or excellent, as stated in the parameter \"relevance of the report\". Some aspects could be improved, for instance, images of collected material evidence or laboratory analytical procedures could be included. These studies allowed establishing a cut-off value for the quantification of the report quality, from which a 100% agreement between the report and the court decision was achieved, in cases where the suspect was found guilty. Finally, the proposed methodology in this work showed a good potential and could be used in other kinds of forensic cases, such as homicide, suicide and other forensic investigations.
