The formal name is 'Independents;' however, most members of the House of Peers were not legally affiliated with any party, and those members could not be distinguished from the members of 'Pure Independents' who were not affiliated with any party including even the faction within the Diet, so the name of 'the Independent Party' was used.
正式名称は「無所属」であるが、貴族院議員は法律上はほとんどが無所属であり、またこの会派も含めたどこの会派にも属していない「純無所属」議員との区別が付かなくなってしまう為にこの名称で呼ばれる事が多い。
