Unapproved works on Urbanisation property

It has come to my attention that someone may be considering doing works on urbanisation property. I have consulted our administrator on this matter and I wish to make my position totally clear.
No-one has any authority to interfere with urbanisation property without permission and certainly when it is in direct conflict with the wishes of the president and works not agreed by the AGM.
If a water test is carried out or any other works done without approval then those people will be accountable for paying the bill and the HC will not pay for any unapproved works.
I cannot allow a free-for-all to develop which could be to the detriment of our urbanisation as a whole.
