Compost Bin

We have a brand new but very ugly compost bin in our common garden area visible to all who come and go. It looks like the 'tardis'; too early to tell if it's going to be on-the-nose.

The plan to get this was alluded to in an agenda for an executive committee meeting but the decision was not actually 'officially' resolved but 'agreed to' for a trial period, it says in the minutes.

It's a nobel aim, I believe, to attempt to recycle this type of waste and use it on our common gardens, but we have many other issues here including fixing residents' other bad rubbish disposal and recycling habits.

My main question, however: should this have been a decision made by a special resolution at a general meeting, not an EC decision?
