On September 21, 2021, the parliamentary Committee on the Public Reward System, the General Flag Days and the Design of the Court's Grant completed its three-year investigation and released a 191-page report with a free-standing 440-page annex.
The annex to the report compiles a legal-historical study conducted by Martin Sunnqvist, associate professor at Lund University, covering dimensions of the monarchy and royal house inclusive of, but not limited to, the constitutional position, prerogatives, and functions of the monarchy; the king, the royal house and family, and the royal household; the development of the relationship between the monarchy and the government; financial grants and disposition of property; the public reward system, orders of chivalry, and medals; heraldry, titles, succession, and marriage.
