Questão jurídica principal
Whether the assistant permit could be extended beyond the two-year limit for a foreign-diploma dentist.
Decisão extraída
The refusal to extend the permit was lawful; the authority could rely on its practice of limiting such permits to two years without renewal.
Fundamentação extraída
Section 29 SanVo allows assistant permits for foreign-diploma medical persons only for shorter periods. The department's practice was based on objective reasons, especially securing training places for Swiss-diploma dentists and avoiding an indirect circumvention of the stricter rules for independent practice. No special circumstances required an exception.
