An embattled Monroe County charter school is taking its landlord to court.

Pocono Mountain Charter School is suing Shawnee Tabernacle Church for overcharging on its rent last year.

The school says it wants to recover the difference between what it paid and what its rent should have been -- a difference of about $750,000.

The school says it should be paying $26,000 dollars per month versus $88,000.

The school has been fighting to stay open amid criticism of its finances.

State Commonwealth Court recently stayed the revocation of the school's charter.
