The bulk of this definition is the general definition of rank-balloting. The
actual definition of MDDA is no wordier than the brief definition that I've
already posted.

Rank-balloting definitions:

To rank a candidate means to assign to that candidate a positive integer
which will be referred to as a "rank number".

To rank X over Y means to assign to X a rank number that is lower than the
rank number that one assigns to Y, or else to assign a rank number to X, but
not to Y.

(Of course there are various ways that ballots could provide to the the
voter, for assigning rank numbers to candidates)

Majority-Defeat-Disqualification//Approval (MDDA):

Balloting:

The ballot provieds a way for voters to rank any or all of the candidates
that the ballot lists--as many or as few as they want to rank.

A voter may give the same rank number to more than one candidate if s/he
wishes to.

A ballot is spoiled and not counted if the voter gives more than one rank
number to one candidate.

Count:

A candidate is disqualified if another candidate is ranked over him/her by a
majority of the voters.
(Unless that rule would disqualify all the candidates, in which case no one
is disqualified)

The un-disqualified candidate who is ranked on the most ballots wins.

In the event of more than one winner, a tie, the tie shall be resolved by
the tie-resolution statute already in effect before this statute's
enactment.

[end of suggested statute definition of MDDA]

By the way, the requirement to not count a ballot that assigns more than one
  rank number to one candidate is included for simplicity.
