I wholeheartedly agree that TRAPs should not be used to challenge the business case of a project. Philosophically, I think it's wrong to suggest that a subway should be constructed instead of a LRT because of a business case, during what is supposed to be an assessment of the environmental impact of the project. So I am glad that TRAP does not allow for that kind of appeal. However, that still leaves for no real mechanism for any citizen to challenge the underlying service and business case assumptions for a given transit project. In the case of the SE LRT, nobody is concerned that it's going to be an environmental disaster or cut through an Indian burial ground. However, some of us are concerned that this project may not be wisest deployment of tax dollars. For us, the options are limited.
