Earlier this month, Seehofer announced his intentions to file a lawsuit within Germany’s Constitutional Court if Merkel failed to restore order at the German borders.
Seehofer told a press conference on Monday that the six-page document will be passed on to the federal government Tuesday for consideration.
"There will be a lawsuit if there is no appropriate reaction," the prime minister said.
Seehofer has been firmly opposed to Merkel’s refugee policy. Earlier this month, he said that Germany could cope with no more than 200,000 arrivals a year.
Germany has been the main destination for thousands of refugees and immigrants coming to Europe since the start of 2015. Bavaria, the key gateway to Germany for those arriving in southern Europe, saw the average of 4,000 new arrivals a day in December.
