A German family has lost another battle in their bid to homeschool their children. 

Since 2006 Dirk and Petra Wunderlich has faced opposition from the German government as they sought to homeschool their children. It is illegal in Germany to homeschool your children.

The family first received a fine in 2006 from the government. They would leave Germany for France in 2009 so that they could continue to homeschool. However, they were forced to return in 2012 after being unable to find permanent employment.

In 2013 over 30 officers and social workers raided the Wunderlich home in tactical gear and forcibly removed the children from the family, according to CBN.

The family was reunited but began a lengthy legal battle. They lost their original case against the German government, and the European Court of Human Rights agreed to take up the Wunderlich case in August 2016.

Last week that court ruled that the family's fundamental rights were not violated by the state.

"It disregards the rights of parents all over Europe to raise their children without disproportionate interference from the state," Robert Clarke, director of European Advocacy for ADF International and lead counsel for the Wunderlich family told CBN in an interview.

"Petra and Dirk Wunderlich simply wanted to educate their children in line with their convictions and decided their home environment would be the best place for this. Children deserve this loving care from their parents."

"It is a very disheartening day for our family and the many families affected by this in Germany," said Dirk Wunderlich, the father of the children.

The Wunderlich still have one option left, and that is taking the case to the Grand Chamber of the European Court of Human Rights.
