Yes, there is a document called Redemptionis Sacramentum, an instruction from the Holy See. It clearly states that it is considered an abuse if a priest or bishop refuses to give Holy Communion simply because a faithful person kneels or chooses to receive on the tongue.
The faithful have the right to request that the priest and bishop adhere to this norm. This is a right granted by the Church to the faithful.
