Could someone point out to me which of points 5 or 15 do apply ? They seem redundant and specify different numbers

King:
Requirements: Must be the in-game faction leader.
Influence: Equal to Authority stat.
Powers:
(1) Can propose an unlimited number of Edicts or Amendments per Council Session.
(2) Can set the build queue and tax rate for all settlements in the King's Demesne. Can destroy any building in those settlements and can rename any of them at any time.
(3) Can call Emergency Council Sessions.
(4) Cannot be banned from a Council Session.
(5) If this rank is held during a Normal Council Session, can Prioritize a total of 8 units per full 10 turn Seneschal term.
(6) Can declare war on any faction at any time, for any reason.
(7) Can veto one Edict or Amendment per 3 ranks of Authority.
(8) Decides which noble, if any, a Princess should marry.
(9) Can allocate all newly conquered land, or let it remain within the King's Demesne if he wishes.
(10) Once during his reign, the King may automatically assume the post of Seneschal for a single term. The King must declare that he is exercising that right at a Council Session; He will then be appointed Seneschal with no election. This right can only be invoked once, but the King can also compete in normal Seneschal elections.
(11) Can ban Nobles from a Council Session. Banned Nobles cannot speak or propose legislations, but they are permitted to vote.
(12) Can adjudicate on disputes regarding Edicts and Codex Amendments. However, if a dispute directly involves the King or the Prince, the Seneschal will be the adjudicator.
(13) Can rename the faction at any time.
(14) Can move the Capital at any time, as long as the new Capital is within the King's Demesne.
(15) Can prioritize 5 units per term.
Penalties:
(1) Cannot hold any other feudal rank except that of Seneschal.
(2) Cannot swear an Oath of Fealty to another Senator and cannot have any Vassals.
Inheritance: On the death of a King, all Oaths of Fealty pertaining to the Noble who is now King are instantly broken, with no penalties. The new King takes control of any provinces in the King's Demesne, as well as retaining those under his control at the time of his ascension. If he was Duke of his House, his named heir for that post attains the rank. In the absence of a named heir, the second in charge of the House becomes Duke.
