1. The competent authority of the host Member State shall grant partial access, on a case-by-case basis, to a professional activity in its territory only when all the following conditions are fulfilled:

(a) the professional is fully qualified to exercise in the home Member State the professional activity for which partial access is sought in the host Member State;

(b) differences between the professional activity legally exercised in the home Member State and the regulated profession in the host Member State as such are so large that the application of compensation measures would amount to requiring the applicant to complete the full programme of education and training required in the host Member State to have access to the full regulated profession in the host Member State;

(c) the professional activity can objectively be separated from other activities falling under the regulated profession in the host Member State. For the purpose of point (c), the competent authority of the host Member State shall take into account whether the professional activity can be pursued autonomously in the home Member State.

2. Partial access may be rejected if such rejection is justified by overriding reasons of general interest, suitable for securing the attainment of the objective pursued, and does not go beyond what is necessary to attain that objective.
