Mae methiannau llywodraethu a rheoli wedi cael eu nodi ym mhob swyddogaeth bron sy’n cael eu harfer gan CWLIDB. Mae’r materion sy’n codi’r pryder mwyaf yn ymwneud â llywodraethu ariannol, sydd wedi arwain at ordaliadau sylweddol i’r cyn-Glerc a’r Prif Beiriannydd, gydag arian cyhoeddus yn cael ei ddefnyddio i dalu am ymweliadau ‘archwilio’ a threfniadau caffael a phrynu anfoddhaol.
Failures in governance and management have been identified across almost the full range of functions undertaken by CWLIDB.  The most concerning matters raised relate to financial governance, resulting in significant overpayments to the former Clerk and Chief Engineer, public funding being used to meet costs associated with ‘inspection’ visits and unsatisfactory procurement and purchasing arrangements.
