The significant importance of international investment has grown rapidly during the last century and consequently, so have the investor-state disputes. International Centre for Settlement of Investment Disputes was therefore established to provide more efficient alternative dispute resolution mechanisms. Understanding the historical background and main objectives of ICSID is essentially important. This is while during the recent decades of its existence, ICSID has been through various challenges. Many aspects of this center have been criticized brutally and many other have supported its role in today’s investment world. In this research we have attempted to point out the current flaws of this institution and the learned lessons. The probable future and upcoming bumps on the road have also been analyzed while possible solutions have been introduced as well.
