With the directives of mod_alias you can only test for the URI path but not the URI query. To do so, you can use mod_rewrite:

RewriteEngine on
RewriteCond %{QUERY_STRING} ^page=cms_page&id=12$
RewriteRule ^$ http://www.example.com/case? [L,R]

The empty query in the substitution will avoid that the original query will automatically appended to the new URI. And the R flag will force an external redirect.
