One of the major issues relating to asbestos in civil proceedings is the latency of asbestos-related diseases. Most countries have limitation periods to bar actions that are taken long after the cause of action has lapsed. For example, in Malaysia the time period to file a tort action is six years from the time the tort occurred. Due to several asbestos-related actions, countries such as Australia have amended their laws relating to limitations to accumulate starting from time of discovery rather than time when the cause of action accrued. The first employee claims for injury from exposure to asbestos in the workplace were made in 1927, and the first lawsuit against an asbestos manufacturer was filed in 1929. Since then, many lawsuits have been filed. As a result of the litigation, manufacturers sold off subsidiaries, diversified, produced asbestos substitutes, and started asbestos removal businesses.
