This book titled, 'Resolving the crises of human rights law within the purview of International Investment Law: A path to reduce fragmentation', has undertaken the work to understand how human rights have not been given due significance in the Investment arbitration jurisprudence. It will study various treaty measures undertaken from 2018 onwards in particular to understand the impact of the remedial measures taken by states to address human rights issues at par with their domestic public interests' commitments. It will provide solutions to fragmentation existing at present. With respect to the same, the thesis shall consider tension or conflict originating between public interest versus private interests. The thesis shall also consider as to how the investment arbitration regime has become more centered towards protection of investors, but again I am countering this argument through a literature review of an article that stipulates as to how home states and host states are now both regaining the ground to regulate the field.
