There has been a lot of discussion about these polls. For instance, for a while the JNE enforced new regulations where people were obliged to give personal information. After protests by poll organisations and the people of Peru, these regulations were nullified since they were seen as an invasion of the privacy by the poll takers. According to the JNE it is not permitted to publish new polls one week before the day of election.
