  Constitutional provisions and authority
  The Ukrainian constitution establishes Ukraine as a unitary state. The specific text of the constitution that refers to the territorial structure is as follows.
  Each of Ukraine's oblasts has its own legislative and executive authority, most of which is subordinate to the central government authorities in Kyiv. Each region is administered under laws passed by the Ukrainian government and the Constitution of Ukraine. Each region levies its own taxes and, in return, receives a portion of its budget from Kyiv, which gives them a portion of the taxes it levies.
