Online Executive Diploma on Law and Neuroscience – A Comparative Approach

Advances in neuroscientific research and technologies have become increasingly important for the field of law. Not only are the number of court cases involving neuroscientific evidence rapidly rising, neuro-legal studies are also used to inform us on substantive legal doctrines, such as the insanity defence. Additionally, the interaction between the law and the neurosciences is highly relevant for criminal policy issues, such as the possible implications of brain research for juvenile offenders or addicts. However, the use of neuroscientific techniques in the legal system is not without its problems, and raises empirical, practical and ethical questions. This Online Executive Diploma on Law and Neuroscience critically reflects on the present and future relevance of applications of neuroscience in the field of law, in particular criminal law. By using a comparative approach, considering both US and European jurisdictions, participants will understand how neuroscientific research may inform criminal justice doctrine, practice, and policy. Fee: $3,650.00 | Next Dates: TBC

International Humanitarian Law

© UN Photo/ Hana Haza’a

War remains a matter of great concern to humanity. Recent conflicts have demonstrated that the ravages of war continue to have a devastating impact especially on the civilian population. War might be the “end of the law” as one said, but International Law is not silent on armed conflicts. From its conception in 1859 on the battlefield of Solferino to contemporary warfare, modern International Humanitarian Law (IHL) has been confronted with significant challenges. Since the times of horses and bayonets to drones and other ‘Lethal Autonomous Weapons System’ (the so-called “killer robots”), the IHL has always had the purpose of regulating the means and methods of warfare in order to limit human suffering. The development and sophistication of weapons has made it paradoxically problematic to distinguish between civilians and combatants in order to better protect the former. In addition, the proliferation of non-international armed conflicts (civil wars) and the emergence of new forms of armed conflicts, i.e. the “war on terrorism”, pose new challenges to the protection of civilian persons and goods. Fee: $650.00

International Law Course - Webinar Track

© UN Photo/Ariana Lindquist

The subject of international law brings a lot of concepts to mind, from war and settlement of disputes between States, protection of the environment, responsibilities and obligations, to human rights protection between citizens, refugees of different States and corporations. Globalization has forced us to interact with each other, making it essential to have common rules to guide and sustain relationships (of trade, investment, technology, etc.) between individuals and States from different regions and continents. Now, many of domestic laws are highly influenced and molded by the rules of international law. International law provides mandatory principles, norms and rules that regulate the relations between States as well as with other non-State actors, like international organizations and individuals. This webinar edition of UNITAR's traditional online course offers participants the chance to ask questions to a high level expert during a Q&A webinar. Fee: $400.00
