After Aberfan the tribunal found the National Coal Board wholly to blame, yet no one was prosecuted, demoted or dismissed, and the chairman's offered resignation was refused. The authors attribute this protection to corporatist politics, the power of the mining unions and ministers' dependence on Lord Robens to run the industry, not to state ownership as such.
The Mines Inspectorate drew on the same mining-engineering profession and assumptions as the Coal Board it policed. It therefore shared the industry's blind spots rather than challenging them. Capture here worked through a common worldview that defined what counted as a hazard, not through bribery or lobbying.
Colliery spoil tips fell outside the mining safety law and inspection regimes, which were aimed at underground working, so no external regulator scrutinised their stability. The Coal Board was still responsible for its tips and had its own safety guidance on them, but failed to enforce it, and earlier tip slides went unacted upon.
The Coal Board and government refused to pay the full cost of removing the remaining tips above Aberfan. About £150,000 was taken from the public donations to the disaster fund to cover it, with the Charity Commission's acquiescence. The money was repaid only in 1997, without interest, which shows how bereaved communities can end up bearing the cost of the responsible institution's remediation.
The Charity Commission treated the Aberfan fund as money to be protected from the bereaved rather than given to them. It questioned whether parents were close enough to their dead children to merit payments and limited sums distributed to victims' families. Legal rules about charitable purpose were applied in ways that frustrated both the donors' intentions and the community's wishes.
After the disaster the Coal Board offered a blameless natural explanation, such as unknown underground springs, made misleading public statements and resisted the tribunal's findings. Once blame was established it worked to minimise its financial liability, and much of this conduct could only be reconstructed once government archives were released decades later.
