Parents have applied for an interim injunction to halt the closure of St Bees School this summer.
The governors of the 400-year-old school had previously said it would close this year, but that they hoped to re-open it in 2016.
But campaigners say by then its long history will be destroyed and confidence in the school lost forever.
Campaigners fighting against the closure of a 400-year-old west Cumbrian Independent school have sent a petition to the Archbishop of Canterbury.
Save St Bees Campaign are calling for Archbishop Justin Welby to support their plan for the existing governing body at the school to resign.
The group argues if this were to happen, they could look to continue providing education on the school site under different governors.
They claim their petition has more than a thousand signatures.
The West Cumbrian school is due to close this summer. The governors say falling pupil numbers mean it is not financially sustainable.
Governors have announced that St Bees School will close this summer.
