This book examines a significant legal topic as it aims to achieve security and economic balance in society. The topic is the criminal responsibility for banking activities in Libyan law. This book introduces the policy of the Libyan legislator in determining criminal responsibility for banking crimes stipulated in the Banking Law and comparing it with what is stated in the Penal Code and other special laws. This is done through extrapolation of the relevant legal texts, to find out their sufficiency and deficiencies, and what they need either by modification or addition. The structure of the book is divided into four chapters. the first chapter provides the background and definition of responsibility and banks, development and their types. The second chapter examines the operations of banks, the nature of their funds, and the criminal character of their employees. The third chapter investigates banking crimes that may occur as a result of a breach of a banking business. The last chapter discusses the basis and conditions of criminal liability for banks and their workers.
