This is a great project. I have a minor suggestion: budget monitoring, or more generally any civil society initiative understood to be around budgets is commonly associated with the analysis and influence of public budgets, ie the goverment's budget that is formulated, approved, executed and evaluated by the government. During all those stages, civil society engagement is critical.

It strikes me that this case study is about political party finance. Without wishing to silo-ise the studies too much, categorise it under 'political parties' might be a useful way to draw linkages with groups working on elections for example, as well as an incentive to located other case studies of groups working around political finance issues.
