Nearly 800 complaints have been filed against the results of the German election on February 23, parliament reported, DPA reported, quoted by BTA.
More than half of these complaints, around 430, concern problems with voting by Germans living abroad.
The Mehr Demokratie ("More Democracy") civic association criticized the shortening of the deadlines for sending postal items, claiming that many ballots from abroad probably did not arrive in time.
The group has launched a campaign calling on affected voters to challenge the results.
"For around 3.5 million Germans abroad "participation in the last Bundestag elections was associated with significant obstacles - for many it was even impossible," the organization said.
The deadline for submitting objections is April 23, two months after the parliamentary elections.
One of the most significant objections came from the newly emerged populist Alliance of Sarah Wagenknecht (AWW), a party that narrowly missed the 5% threshold needed to win seats in the Bundestag. The AWW argues that a recount could put it over the line, which would change the balance of power in the Bundestag and potentially take away the majority of the future coalition.
According to the official result, the party had collected 4.972% of the vote, falling some 13,400 votes short of the 5% threshold.
