Anything is arguable, but I don't think this statement is correct. An IRV winner has a "quota" of 50% + 1, whereas the
first stage winners in most STV-PR elections will have only the relevant Droop quota. Also, in STV-PR several
candidates can be elected at the first stage, and frequently are. In the 2003 elections to the Northern Ireland
Assembly, two candidates (out of six winners) were elected with quotas of first preference votes in each of 6
constituencies and three candidates were so elected in each of 3 constituencies.

Ireland has posted the full ballots only for the three constituencies that used electronic voting machines. All the
other constituencies used conventional paper ballots that were sorted and counted manually. When STV-PR is introduced
for Local Authority elections in Scotland in 2007 it is planned that the paper ballots will be scanned and processed
electronically. The legislation is being drafted at present, but there will be a campaign for full disclosure if that
is not included.
