Laravel - Midlleware called after controller construct

I have trouble with checkauth controller that are called after SectionsController constructor - from this is extended ReportController and I don't know why it works like this. I try add middleware at the start of SectionController costruct like $this->middleware('checkauth'); but not working too.

Middleware

<?php

namespace App\Http\Middleware;

use Closure;
use Auth;


class CheckAuth
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (!Auth::check())
        {
            return redirect('/admin/login')->withErrors(['message' => 'You need to login before proceeding']);
        }

        return $next($request);
    }
}

ReportController

<?php

namespace App\Http\Controllers\RMReport\Form;

use App\Http\Controllers\RMReport\SectionsController;
use Illuminate\Http\Request;
use Illuminate\Support\Str;


class ReportController extends SectionsController
{

    public function __construct(){
  /*     dump("REPORT CONTROLLER:");
       dump(\Auth::check());*/
      parent::__construct();
    }
.
.
.
}

SectionsController

<?php

namespace App\Http\Controllers\RMReport;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Support\Facades\View;
use App\Http\Controllers\Controller;
use Illuminate\Http\UploadedFile;



class SectionsController extends BaseController
{
  use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function __construct(){
      $this->middleware('checkauth');

      dump("SECTIONSCONTROLLER: ");
      dump(\Auth::check());
    }
}

Output from route:list

GET|HEAD | admin/remote-report/{id?} | rm.report | App\Http\Controllers\RMReportFormReportController@form | web,checkauth,checkownerRMreport |  
POST | admin/remote-report/{id?} | rm.report | App\Http\Controllers\RMReport\Form\ReportController@store | web,checkauth,checkownerRMreport |

Output on call GET

"SECTIONSCONTROLLER: "

false

"CHECKAUTH:"

true
