# MIP4c2-SP27: MIP16 Amendment Subproposal
This is a summary of the subproposal and its effects upon ratification from GovAlpha's perspective:
- This is a valid [MIP4c2](https://mips.makerdao.com/mips/details/MIP4#MIP4c2) subproposal.
- This MIP amends [MIP16: The Weekly Governance Cycle](https://mips.makerdao.com/mips/details/MIP16) by adding two bulletpoints to MIP16c1.
- This proposal intends to override community-triggered Signal Requests (community actions resulting in non-standard Weekly Polls) by making them specifically limited to existing provisions in MIP process. This means that Signal Requests that are **not** specified in a ratified MIP will no longer be permitted.
- This proposal has been assigned `High-Impact` based on the methodology listed [here](https://forum.makerdao.com/t/introducing-impact-estimations/14267).
