To prevent councils from finingnthe homeless erecting tents.

Many councils, such as Stoke-on-Trent City Council, are planning to fine the homeless (£1,000) for erecting tents, donated by charities to shelter from the cold. The impact of this plan will:

(A) criminalise the most vulnerable in our society
(B) clog up our legal system with cases

We can't accept your petition because the UK Government and Parliament aren't responsible for the issue you raise. This decision is the responsibility of local councils.

In any case, it appears that the local council in the specific case you are concerned about has decided not to do this. You can find out more here:

If you'd like councils not to be able to make this decision, you could start a new petition asking Parliament to change the law.
