A more thorough explanation:

quare obstruxit

Quare obstruxit is a legal term that means "why he obstructed." It refers to a writ that was used when someone was unable to use a path through their neighbor's land because the neighbor had blocked it.

For example, if a farmer had been using a path through their neighbor's land to get to their own fields, but the neighbor put up a fence that blocked the path, the farmer could use a quare obstruxit writ to ask the court to order the neighbor to remove the fence and allow them to use the path again.

Another example would be if a person had a right to use a road that went through their neighbor's property, but the neighbor put up a gate that prevented them from using it. The person could use a quare obstruxit writ to ask the court to order the neighbor to remove the gate and allow them to use the road again.

These examples illustrate how quare obstruxit was used to protect people's rights to use paths and roads that went through their neighbor's land.
