Scrapping the Human Rights Act in the UK would diminish its reputation, Nicola Sturgeon will warn on Wednesday.
In a speech in Glasgow, Scotland's First Minister will say "no responsible government should even be considering such a step".
She believes the plan, an election pledge by the Conservatives, creates a "completely unnecessary dilemma" and "addresses no obvious problem".
"There is instead a clear risk that it will create legal confusion; harm people in the UK who need support and protection; and give comfort to illiberal governments around the world," Ms Sturgeon is expected to say.

"One of my fondest memories is of the two of us skiving off to see Trainspotting in a Melbourne cinema.
"And I think we were the only two Scots in the audience at the time and we got a lot of strange looks as we were laughing uproariously at jokes nobody else was getting. That's a nice memory that I will always treasure."

Scotland's First Minister has insisted David Cameron has "no right" to rule out a second independence referendum.
Nicola Sturgeon said she was "not planning" to hold another such ballot but refused to rule it out - claiming it was up to the people of Scotland to decide.
The SNP leader told ITV's Loose Women: "We had that debate and that vote last year, and Scotland, against my better efforts, opted to stay part of the United Kingdom, to stay part of the Westminster system
She added: "I'm not planning another referendum. Why I stop short of saying I absolutely guarantee it is the same reason I don't think David Cameron has got any right to rule it out.
"Whether there is another referendum or not is really down to what people in Scotland want, there can't be another referendum unless people vote for it.
Nicola Sturgeon says it is time for "an alternative approach" as the SNP's newly-elected MPs prepare for a photocall to celebrate their win.Read the full story ›
