who here actually knows how the system of land and building distribution actually works?

I know of a school that was sitting for many years in a plot of land with temporary structures. A couple years ago they received a permanent plot and built on it a new school building. They just completed it and moved in over the summer in time for the new school year.

I would think that the original plot should now revert back to the iryah and be prepared for re-allocation for the next school in line that needs a place.

Yet that is not happening. There might be things I dont know about what is going on, but at the end of the day the school administrator is renting out the original plot to a shul for Shabbos and to a relatively new and small yeshiva ketana.

Why does he have the right to do this?

This plot, or others like it, could be used to solve the crisis of other schools. Maybe the schools sitting on the Mishkenos plot can be moved there so the Iryah (or whoever) can start building  the new Mishkenos building. Maybe Misheknos can use this location for some of their classes. Maybe it can solve the problems of space other schools are having (Moriah? others?) Maybe it can be used to solve the property dispute between the two talmud torahs that happened recently and one of them can move in to this plot. Maybe it can be used as a temporary location for one of the many schools waiting to build a building but nowhere to move to in the meantime.

There are is a plot across from the Merkaz Mischari. It was used for  a school. When the school moved out to its permanent location, the admin there also tried to rent it out. The locals, led by Rabbi Goldstein, fought him on it. They wanted it for Mishkenos, though obviously they never got it. I dont know what happened to it, but it looks pretty empty when I pass by. This location too could be used for solving some of the problems.

Yet instead of reallocating it to a school in need, the administrator who originally held it gets to rent it out to the school of his choice. I dont think this yeshiva ketana can even make full use of the property, meaning much of it is probably being wasted and sitting empty.

And I am sure that if I know about one or two such situations, there are probably others similar..

So, who knows how the system actually works, and how such a situation can exist?
