Revision with unchanged content. The Sarbanes-Oxley Act 2002 established new regulations concerning the treatment of whistleblowing employees and lawyers. The main objective for these new mechanisms was to prevent further corporate scandals as recently happened in the USA. Employees and lawyers are supposed to contribute an important part in terms of monitoring corporate conduct. This essay traces the reasons behind the critique of whistleblowing regulations under the Sarbanes-Oxley Act 2002. It shows that the newly adopted rules are not capable of establishing a working concept for monitoring corporations ‘from the inside’. The Sarbanes-Oxley Act does not provide sufficient protection for employees who blow the whistle against retaliations by their employers. It failed to establish procedures to ensure that whistleblowing will no longer be ignored. Furtehermore, this essay shows that the current requirements for lawyers are not effective in terms of monitoring corporate conduct. Lawyers will most likely stay reluctant to disclose confidential information. The essay shows that outside reporting rules for lawyers significantly endanger the attorney-client privilege and cause considerable problems for non-US lawyers. At the bottom, the Sarbanes-Oxley Act failed to establish a working regime of the promising idea to monitor corporate conduct from the inside.
