But it sounds like these people are more concerned about you obeying thier power than running the allotments fairly and all to often in situations like this where ignorant people have power , fighting their judgement will make them act even more despotic and even if you win the day they will find every opportunity to harrange you in the future. So consider your future really well have a look around at other sites and have a plan b. Not all allotment sites are run by power mad emotional morons and maybe finding a new site would make your time on the plot much less stressful.
If others confirm that the warden has a record of troublemaking, that definitely calls for a complaint to C or E officialdom. See if you can get him kicked out again!
^^ sorry for my rant, it is just that our money is funding this persecution. If only you were a black lesbian single mother FTM.
