The Committee for Plundered Ministers was originally established in late 1642 by the Presbyterian faction in the Long Parliament following the start of the English Civil War.
If the allegations were proved, the rector was replaced and his property forcibly sequestered, so that he could only recover it by buying it back.
The committee also acted as trustee, allocating money collected from rent of rectory lands to support priests in their roles throughout Britain.
These sequestrated clergy were described as "scandalous", which meant that either they supported the Royalist cause, or their theological attitudes were high Anglican, or both.
An example of the worst sort of "scandalous" behaviour (from the point of view of Parliament and its supporters) was Griffith Williams, who at the start of the Civil War was Bishop of Ossory.
