Prosecutors decided not to pursue criminal charges, with 24-year-old Kulke's attorney maintaining that one of the reasons for the dropped charges was the absence of "No Trespassing" signs placed around the property's perimeter, reported TMZ online.
He argued that this led Kulke to believe he could enter. Another reason for this is that Swift's family reportedly did not want to move forward with the case.
However, prosecutors still could reopen the case if new evidence or information is found in the 12 months to come.
Although the trespassing incident has been resolved out of court, Kulke remains in jail as he's facing extradition to Colorado for probation violations including robbery back in his home state. He is scheduled to appear in court on January 29.
Kulke was taken into police custody earlier this month for trying to climb over the fence of Swift's Nashville house. He told cops he is her boyfriend and had taken a bus from Wisconsin to be with her on her 23rd birthday.
The 'Love Story' hitmaker was miles away with her real boyfriend, Harry Styles, in UK back then.
