-\todo{Mention ML certificate property}
+One aspect making \ac{LP} decoding especially appealing is the very strong
+theoretical guarantee that comes with it, called the
+\textit{\ac{ML} certificate property} \cite[Sec. III. B.]{feldman_paper}.
+This is the property that when a valid result is produced by an \ac{LP}
+decoder, it is always the \ac{ML} codeword.
+This leads to an interesting application of \ac{LP} decoding to
+approximate \ac{ML} decoding behavior, by successively adding redundant
+parity-checks until a valid result is returned \cite[Sec. IV.]{alp}.
