SDCL § 1-32-4: Changes in organization or functions within departments.

In order to promote the efficient administration of the principal departments, the Governor may establish, combine, or abolish divisions, offices, or other administrative subunits, with the exception of boards and commissions authorized by the Legislature, and may allocate and reallocate powers and duties among divisions, offices, or other administrative subunits under the various principal departments if the reallocation of powers and duties allows the departments to continue to perform the functions assigned and mandated by the Constitution and laws of the State of South Dakota.
