Litigation Related to System/Software Development

As described in the System Development section, there is often “information asymmetry” between the user company and the vendor company in system development. The user company that entrusts system development to a vendor may have little knowledge and knowhow of information technology, while the vendor company that undertakes system development may have little knowledge about the growing complexities in operations of the user company.

In litigation, it is first necessary to gain the court’s understanding of the above-described premise, and then to carefully unravel what happened on both the user side and the vendor side in each case.

Another characteristic of system development-related litigation is that documentary evidence submitted to the court is often written in technical terms and based on concepts that are understandable only to those with specific knowledge in the field. There are also cases where documents are written in English when overseas vendors are involved.
