Is it better to use “who” in this context:
The practical effects should be found in partnerships with the regional, local and urban authorities who/that should get involved in the elaboration…
Thank you!

I would probably use ‘who’ there.

Hi Stejar33,

Clearly ‘who’ and ‘that’ are both relative pronouns and can often be used interchangeably. ‘Who’ in your sentence makes better sense because it simply links the ‘authorities’ with the idea of ‘getting’ involved’. The use of ‘that’ points more to the idea of defining the previous noun and making a distinction. You could continue with the comment in your sentence by adding … There also other authorities that don’t get involved …
