Objective: The current paper assesses the agreement rates between the outcome of psychiatric expert opinion and the final judicial sentence and reports two typical cases, one of agreement and the other of disagreement between judges and forensic psychiatrists. Methods: All verdicts involving forensic psychiatric evaluations in circuit courts of Campinas (SP) in the year 2002 were studied. For the year 2002, from a total of 133 criminal trials that had psychiatrical evaluation in that year, 41 verdicts were studied according to its socio-demographic characteristics, clinical data, and type of crime and possibility of imputation. Results: A high rate of agreement was observed between legal capacity and judicial sentence, a result similar to that found in the literature. Conclusions: From this preliminary study it is possible to conclude that judges in the Brazilian social, cultural and legal context seem to agree completely with the assessments and conclusions reached by forensic psychiatrists in criminal forensic cases. High-profile or very severe cases appear to be exceptions to this rule. Studies with larger samples and from different regions in Brazil must be performed in order to verify whether this data is valid on a national level.544306310Abdalla-Filho, E., Engelhardt, W., A prática da psiquiatria forense na Inglaterra e no Brasil: Uma breve comparação (2003) Rev Bras Psiquiatr, 25 (4), pp. 245-248Amaral, A., Crime e patologia (1987) J Bras Psiq, 36 (2), pp. 115-117Appelbaum, P.S., The Supreme Court looks at psychiatry (1984) Am J Psychiatry, 141, pp. 827-835Cohen, C., Ramos, M.R.R., Considerações acerca da semi-imputabilidade e inimputabilidade penais resultantes de transtornos mentais e de comportamento (2002) Revista Brasileira de Ciências Criminals, 39 (4), pp. 215-229Oliveira, J., (1998) Código Penal Brasileiro, , São Paulo: Editera Saraiva(1993) Classificação de Transtornos Mentais e de Comportamento Da CID 10, , Porto Alegre: Editora ArtmedPikona-Sapir, A., Melamed, Y., Elizur, A., The insanity defense: Examination of the extent of congruence between psychiatric recommendation and adjudication (2001) Med Law, 20 (1), pp. 93-100Reich, J.H., Tookey, L., Disagreements between court and psychiatrist on competency to stand trial (1986) J Clin Psychiatry, 47 (1), pp. 29-30Rigonatti, S.P., Serafim, A.P., Barros, E.L., (2003) Temas Em Psiquiatria Forense e Psicologia Jurídica. 1 Ed., , São Paulo: Editora VetorTaborda, J.G.V., Chalub, M., Abadalla-Filho, E., (2004) Psiquiatria Forense. 1 Ed., , São Paulo: Artmed EditoraTeixeira, E.H., Barbi, K.S., Pereira, M., Folie à deux: Dupla tentativa de infanticídio (2004) Apresentado No XXII Congresso Brasileiro de Psiquiatria, p. 444. , Salvador, BA(1976) Lei de Tóxicos - Diário Oficial Da União, , Lei no 6.368/76(1984) Lei de Execuções Penais - Diário Oficial Da União, , Lei no 7.210/84(1995) Juizados Especiais Civeis e Criminals - Diário Oficial Da União, , Lei no 9.099/95
