You have an important role to play in the consultation process of The Scout Association. The 'policies and rules' for scouting are made by the national board of trustees which are elected by the Council of The Scout Association.
Our County Commissioner meets at region level (we are in the South Western Region), about three times a year at these meetings the other County Commissioners in South West and the Regional Commissioner discuss the needs and concerns for scouting in our Region which have been brought to their attention. The Regional Commissioner then represents the views of the region at national meetings of the 8 Regional Commissioners and the UK Commissioner for England. Who in turn feeds them back to the UK Chief Commissioner.
In the same way, as a Group Scout Leader you attend District Leadership meetings and share your concerns and needs with the other GSLs, Commissioners and our District Commissioner. If the issue is just a concern in the district normally the GSL and DC make a decision. If the issue is concerning a county or national policy or procedure the DC will take these items to the Avon County District Commissioner meetings and again, if the issue is a concern in the county normally the DCs and CC make a decision. If it is a national issue the CC will take the item to the regional meeting for discussion for the RC to take to the national meeting.
Good ideas and ways to develop scouting need to be talked about and fed into 'the system' at all levels. At each stage it is the majority view which must go forward. A good idea from your group might be disagreed with when others in the district are consulted. The process outlined above does take time but ensures that the best decision is made for the young people in scouting.
As you can see, the 'system' is a vast network, which encourages people to talk, communicate and discuss the development of scouting. Consultation is important and it is vital you play your part.
Remember to give leaders feedback and reasons why things have or have not happened. It is helpful to give purposes when communicating on any issue for the purpose gives real understanding to why the decision was made.
